  2. Hi LoSpo,

    The tzap command I gave in the example tunes to BBC ONE in the UK and the dvbstream command demultiplexes this signal using parameters specific to that channel. As I’m assuming that you don’t live in the UK then this test is not relevant for you.

    As that section is mainly for testing/debugging the tuner card, I’d skip it and continue with the MythTV installation. See how it goes.


  3. Hi.

    First of all, thanks for the great guide. I have used it to set up both my combined frontend/backend box, and an EPIA frontend.

    I am still using edgy, and I just upgraded myth. All is fine, apart from I can’t access mythweb any more. I remember having to do a hack to the file permissions, but this hack doesn’t appear in the latest guide. Can you remind me what it was?


  4. Hi
    Still using your guide, it’s the best on the net!
    How does one apply the xtraview patch as found at http://brej.org/dvb/index.html
    With out breaking my newly finished under tv mythbuntu box.
    3 turners, 1 nova t 500 and a Kworld
    I also really need to understand how to get the 7.1 on board Realtek ALC883 working.
    I’m trying to replace a windows DVD system, that has no bother with bouncing the sound around the the room

  5. Hi Alec,

    Thanks. As far as I know, Xtraview was canned almost a year ago, so the patch is useless nowadays. Regarding the ALC883, I don’t have that, so I can’t really help. Sorry.


  6. Thanks, how about the red hot channel, it was in the clear on my old set up but not now? I know it’s crap, just like to get everything working?

  7. Not sure about that. Maybe it would work, but I think that the patch is for an old version of MythTV, so wouldn’t guarantee anything. You might be able to find one somewhere, though.


  8. BTW, had you noticed the new MythTV metapackages that come with Gutsy? There’s now separate ones for a master backend and slave backend install (both of which I’ve tried) and a Mythbuntu Control Centre (which I haven’t).

    Also, MythTV 0.21 is scheduled for release “before March 2008″, which promises autodiscovery of remote backend/tuners, among other things. Hopefully that will at last mean that I’ll be able to use the tuner in my slave backend…

  9. They’re doing some great work with the MythTV packages. It makes a great change from the bad old days when the Ubuntu packages were a version out-of-date.

  10. The clearest guide I’ve found, and I’m bitterly sorry it took me so long to find it :( It’d be nice if a link to your site was more visible on the Mythbuntu documentation.

    The only problem I’ve run into since coming across your guide is with the remote. I’m sure I must be missing something obvious.
    With a clean Mythbuntu installation I set the remote to an Hauppauge Nova-T 500. I found out later that this isn’t the same as my Nova-T.
    The direction buttons & OK work, but nothing else.
    I followed your guide for setting up my remote and irw returns all the correct values. All the buttons seem to work fine.

    However, when I start the frontend the remote doesn’t work at all, and a quick trip to the Mythbuntu Control Centre shows that the remote has been disabled.

    Re-enabling a remote (relevent choices seem to be Hauppauge DVB-s card, Hauppauge Nova-T 500 or Hauppauge TV card) in the control centre stops irw from working, but brings back the directional buttons & OK.

    Any ideas what I’m missing?

    Thanks for the brilliant site, I’ll need to look for better hardware soon and this will be my first stop.

  11. Hi

    Great guide, particularly the section on Nova-T which was extremely useful. I have a panasonic 32inch LCD TV, when connected via a DVI output I only get 640×480 resolution – what resolution do you have while connected to your panasonic tv? I got much higher resolutions with my previous CRT based panasonic tv – I’m not sure why!

  12. Hi Andy,

    Glad you found the guide useful.

    When using the tv-out with your old CRT TV, even though the resolution was set to, say 1024×768, what you were actually seeing would be a PAL representation of that – and I bet it was pretty fuzzy when on the desktop.

    LCD TVs tend to have lower native resolutions than monitors, but yours should be higher that 640×480. You may need to find a specific modeline for your TV and put it in your /etc/X11/xorg.conf. Have a search for your TV to see if you can find one.


  13. Please take in account i am new to linux and mythtv and desperately need assistance.

    After installing mythtv on my gusty installation i get to the portion of your guide where i am to run mythtv backend setup. I am then asked to select my language then i am shown the Database Configuration pages 1 and 2. which reads “myth could not connect to the database. please verify your database settings”. I dont get the menus shown in your guide. what am i missing?

    Thanks in advance for your time and help

  14. Hi Chauncey,

    Sorry for the late reply, I’ve been away for the weekend…

    Not sure what went wrong, but the first thing I’d do would be to see if you can log into the database manually:

    Get the MySQL user and password for Myth:

    cat /etc/mythtv/mysql.txt

    Try to log in:
    mysql -u mythtv –password=fgugnbbg

    (change the above to use your password obviously)


  15. garry,

    great guide!!!!

    but … i do have the same problem as chauncey and i could NOT log in to mysql

    cat /etc/mythtv/mysql.txt

    mysql -u mythtv -password=VmsHZ27L
    ERROR 1045 (28000): Access denied for user ‘mythtv’@’localhost’ (using password: YES)

    could you help me?

  16. There should be 2 minus signs before “password”:

    mysql -u mythtv –password=VmsHZ27L

    Also, try this command to log directly into the mythconverg database:

    mysql -u mythtv –password=VmsHZ27L mythconverg

  17. garry, thanks for the quick reply!

    unfortunately still no access:

    mysql -u mythtv –password=VmsHZ27L
    ERROR 1045 (28000): Access denied for user ‘mythtv’@’localhost’ (using password: YES)

    mysql -u mythtv –password=VmsHZ27L mythconverg
    ERROR 1045 (28000): Access denied for user ‘mythtv’@’localhost’ (using password: YES)

  18. Hi Gary

    Question: Does your Nova-t remote wind the volume up and down without taking your finger off the button?

    Mine does not, I have set the repeat in lircrc from 1 to 30 with no change, also it often miss reads the input and skip’s back or forward if you push tje button up or down repeatedly too fast.

    Any idear’s


  19. Hi Alec,

    I only ever use the volume on my TV remote, so I can’t say off the top of my head. I’ll give it a try tonight.

  20. I have a working mythtv setup using gutsy and WinTV-NOVA-T model 909. Sometimes I will record a program and when I play it back the picture is broken up. After some experiment I have found that if the aerial is plugged directly into the TV the picture is always good but when plugged into the Nova-t the picture sometimes degrades. An example was on Monday last the kids were watching Star Trek on Virgin 1 and the picture and sound were all disjointed, I moved the aerial to the TV and the picture and sound were Ok. Any ideas.

  21. Hi Peter,

    Hmmm… sorry, I find the opposite is true – my Nova-T is less susceptible to interference than the tuner in my TV!

    Anyway, it looks like a signal strength problem. You can confirm this by pressing F7 whilst watching a channel to see the signal status.

    Maybe a powered signal booster would help (I use one to split my signal between my TV and my first Nova-T card).

    The quality of your aerial cable can also affect the signal quite significantly.

  22. Hi Alec,

    Sorry for the late reply – been very busy recently…

    Anyway, I’ve got my repeat set to set 3 and it works fine. A repeat of 1 would register every event while you have the button pressed down, so it would be too fast. If you set it to 30, it would be way too slow. So, 3 seems to work fine for me. It’s a good setting for up/down in the menus, too.


  23. Hi Garry, great guide, i have a similar install on the original pundit with onboard sis650 and at present a single Nova-T dvb card.
    Ive always had a nightmare with the remote of the nova-t, the main part being the interference caused when buttons are pressed whether that be changing channels, pausing TV, pretty much anything. The screen (a 37″ LCDTV) goes blank for a few seconds. Just wondered if you had encountered this or anything similar, thanks

  24. Hi Craig,

    This is the first I’ve heard of interference when using the remote control… Unfortunately I don’t know what to suggest!

    Does the problem affect Xine/mplayer etc or just Myth? Have you tried running irw and then pressing the buttons? Do you still get the problem?

  25. interference is probably not the best choice of word. It occurs even when browsing through the menu in myth, the screen goes blank for a second of two. when you do irw it recognises all the key presses and this doesnt occur in mplayer or xine wether they are run from myth or standalone. Im going to try another tv and also looks at the keymaps in myth to see if there is anything there

  26. Hi Garry

    I had a further play around using a MCE remote, configured lirc and still the same issue. However, it doesnt affect mplayer or xine. Only when using myth, either navigating through the menu or watching tv. Basically any button causes the creen the either flicker, jump or go blank for a moment or to. The only other thing i can try is another tv, perhaps a crt style and not an lcd

  27. I printed out your guide, but only got as far as the third page. (MythTV Setup) After I run the MythTV Backend Setup, I get a Terminal window full of error messages rush past:

    No error type from QSqlError? Strange…
    2008-02-06 11:06:17.061 Database not open while trying to load setting: GuiOffsetY
    2008-02-06 11:06:17.061 Unable to connect to database!
    2008-02-06 11:06:17.062 Driver error was [1/1045]:
    QMYSQL3: Unable to connect
    Database error was:
    Access denied for user ‘mythtv’@’localhost’ (using password: YES)

    I then select my language and it tells me ‘Myth could not connect to the database. Please verify your database setting.’

    I tried KnoppMyth already, (“20 minute autoconfiguration”, my ass) but never could get the TV guide scripts to work because I bought an analog dual tuner instead of two digital tuners.

    I don’t seem to have much luck with this digital home theatre… I’m beset by puzzling error messages at every turn, and feel very frustrated. I was hoping ubuntu’s installation scripts would be a bit more intelligent, but apparently it still takes some heavy lifting to get anything working.

  28. Hi Marco,

    I’m sorry that you’ve had so much trouble.

    MythTV on Ubuntu usually goes as smoothly as anything. However, I’ve had quite a few people complain about this recently. I’m beginning to suspect that one of the packages is broken somewhere. I’d like to confirm myself, but I’m moving house in a couple of days and don’t have the time to build a test box from scratch!

    Anyway, see the following guide. It should help you get your database access sorted out:


  29. Hi Garry,

    I’m pretty sure that I’ve worked out what the problem is that is causing so many people grief – you’ve missed out a step in your instructions! There are *four* dialogues in the ‘installing MythTV’ section – the first one is the root password. Just hit ‘enter’ for it, and that solves the problem.

    I think what has been happening is that people have been entering in a password. If you don’t, it works fine. At least, this is what I did that gave me the same error that everybody else is getting.

    This fixed my problem after I removed all MythTV and MySQL files installed (including configuration files) and redid it.


  30. Just a quick advance report on Hardy:

    I got forced into using the alpha6 release of Hardy because my master backend machine suddenly decided that it wouldn’t run Edgy, Feisty or Gutsy any more – even from LiveCD.

    The install of MythTV 0.21 worked fine straight out of the repositories, and Mythbuntu also works well, with it’s own dedicated Control Centre.

    Good bits: Slave backend auto discovery works, and there quite a few tweaks and improvements in many other areas.

    Bad bit: The network protocols have changed again, so a version 0.20 frontend or slave backend won’t work with a 0.21 master backend. Ok, I know I should expect this but I was hoping otherwise, as I don’t really want an alpha release on all my PCs!

  31. Hi Martin,

    Thanks for that. I’m way off taking the plunge myself!

    I can understand your frustration regarding the frontends not being compatible. You could compile 0.21 from source – easier than it sounds – but I guess it depends how much you use the frontends and whether you can wait until April for Hardy to be released.


  32. I posted that a day too early! Just noticed that an auto-update to Gutsy today, taking the Frontend from 0.20 to 0.21. Not sure if everyone gets this, or only those running a 0.21 backend – but I can’t see how the updater would know that…

    The themes on the new frontend appear to be broken, in that in my case it reverts to having only Gannt and Blue available, even with mythtv-themes installed. I ~think~ you now have to enable the other themes in the Mythbuntu Control Centre, but don’t want to test that on this PC, as I don’t want to risk turning it into a “Mythbuntu appliance” (as I accidentally did with my master backend machine!).

  33. Hi Martin,

    Strange, I can only see 0.20.2 in my repos, so I’m not sure where it’s getting the new version from. Maybe it’s a Mythbuntu thing?

  34. Hi Garry,

    I don’t think it can be anything to do with Mythbuntu, as this PC’s not running that. It was a bog-standard 0.20 frontend (and is now a 0.21 frontend with some not-so-nice themes). If I go into Synaptic I see most of the myth components at release 0.21, even though this PC is still running Gutsy.

    So it seems that credit is due to the developers in the way that they handled the upgrade – there seems to be a mechanism whereby a frontend “knows” that it’s mismatched with the remote backend and requires the update.

  35. Hi Gary,

    Thanks for the guide it was really helpful. Just to let you know I had the same issue with connecting to the mysql database that everyone had. I did enter a root password and suspect Anthony is right in his post above. I am happy to say that running through the instructions in the troubleshooting link you posted above solved it for me.

    Thanks again for all your work

    Brian M

  36. Hi Brian,

    Thanks for the confirmation. I know that I really need to add this info to the guide, but I’ve been unable to do so due to problems with my internet connection from home.

    Hopefully the RJ45 plug crimping tool I’ve just borrowed should go some way to sorting it out tonight so that I can get on and update the guide!


  37. Hi Gary

    Here one for you?
    I have just built from old parts an Ubuntu server and using LVM packed it full of old hard drives, that will contain ripped dvd’s.
    Is it possible to have a link in the videos folder within Mythbuntu to link to this shared folder on my network?
    I plan to get about a Tb of films on this server and would like to be able to “stream” them at will. but I don’t want to change the video folders location in mythbuntu’s set up.

  38. Hi Alec,

    Do you want the folder to be accessible by Linux or Windows machines? For Linux, you can share the folder using NFS. For Windows, share it using Samba. I won’t go into the commands as there are there are plenty of tutorials on the subject which will be more comprehensive than I could be here.

    I have a 500 GB external USD drive to store my DVD ISOs. This is plugged into my Myth box and shared using NFS. I can watch these on my Ubuntu box upstairs using VLC no problem.

  39. Hi Gary

    Its shared with samba, as I use windows to rip the dvds. I was hoping to put a link to this folder in the videos folder, so when I go to it with the remote it opens the samba //ubuntu/dvds/ folder for the dvds.

    So if could point me in the direction of the tutrial of how to make that link file. that would be great. I’m still trying to get my head around linux. sort of wish that linux was an option when I upgraded from my Dragon 32 all them years ago.


  40. Hi Alec,

    I’m confused now – Are we talking 3 machines here? An Ubuntu machine to store the DVDs, an Ubuntu machine as your MythTV frontend and a Windows machine to rip the DVDs?

  41. Hi Gary

    Yes I have 4 pc’s on the network, Mythbuntu 710 as frontend and backend , ubuntu server(file server), ubuntu gutsy descktop (that is trying to take over from the windows pc), windows xp ( that I use for work). Plus the xp laptop when it not traveling around in the car, fixing PLC’s for work.

    I’m trying to replace a Netgear network hard drive unit that only talks to windows or through windows and is very slow

  42. OK, so…

    - share the drive using samba so that Windows can write to it.
    - also export it using NFS so that you can mount it on your frontend.
    - go into settings on mythfrontend and change the video directory to your mounted directory.

    Here’s a few tips on achieving this, assuming that the directory holding your DVDs is /store/dvd on a machine called fred:

    On the server (fred), install nfs-kernel-server:
    sudo apt-get install nfs-kernel-server

    …and add something like the following to /etc/exports:
    /store/dvd *(ro)

    - pick up the changes:
    sudo /etc/init.d/nfs-kernel-server restart

    Check that it’s shared:
    showmount –exports

    On the client (frontend machine), install nfs-common:
    sudo apt-get install nfs-common

    …and mount the directory:
    sudo mount fred:/store/dvd /mnt/dvd


  43. Thanks Gary.

    That was great, I got it working, did not have much with luck with
    showmount -exports
    returned an error, but the front end can see it anyway.

    Now is it possible to have the frontend look at /var/lib/mythtv/videos and in that folder see a folder that takes it off to the shared LVM drive ~/dvd on the server?
    And how do I make the frontend mount the ~/dvd on boot up, I find that it still hangs from time to time.
    This is the latest 7.10 64bit release downloaded in March 08, it’s better in that the hanging is far less frequent and the remote repeat works but now the Guide is very very slow??

    Thanks for all your help


  44. Hi,

    If you try adding a symbolic link from the videos directory to your mounted dir:

    cd /var/lib/mythtv/videos

    sudo ln -s ~/dvd

    It *should* work. Give it a try.

    You can add the NFS mount command to your /etc/fstab to get it to mount on bootup. Googling for “fstab NFS” should give you the commands.

    What’s hanging? Are you still talking about NFS?

  45. Hi

    No its mybuntu that hangs, just freezes normally while watching TV.
    I get problems when playing DVD’s if the disc is damaged half way through a film, but so did the old windows system.
    The main worry is the guide, it becomes non responsive for a time, then all the key pushes it recived during that time all happen at once, then it becomes non responsive again only maybe 3-4 mins each time. But other times it works fine. I have no idea why yet.

    Thanks I’m off to try the symbolic link now

  46. When it hangs, can you switch apps (using alt-tab) or get to the console using ctrl+alt+F1 ?

    If not, it may be a graphics driver issue. Make sure you’re using the restricted drivers and also that you don’t have Preference->Visual Effects set to “none”.

    Also, search around for issues with your exact graphics card under Myth.

    Hardy is out on Thursday. That might be worth a try.

  47. I will try that, there is no keyboard attached, so can I try via VNC? and if say I can get to the console err how do I get back, without rebooting like I just did on this machine,, stop laughing.

    I’m using the restricted drivers, Nvidia. I’ve not changed any of the default setting so I guess Visual Effects is at “none”

    Yes I will be upgrading to Hardy, and the Mythbuntu version as soon as it’s out of Beta. Maybe that will cure all woo’s

  48. To get back from the console it’s ctrl+alt+F7. (sometimes it’s F8 or F9).

    Maybe it’s worth connecting a keyboard for debugging purposes… I’m not sure that VNC would work.

  49. Hi
    I’m having a little trouble with scanning the changels,. IThe Mythtv is connect to a sky+ box using the svideo ports. But when I scan in Mythtv I get SE1 -SE41 and not the channelsl listing in the guide. Is there somethings are doing wrong.


  50. Hi Garry,

    I used the guide for 7.10 and things seemed to work pretty well for a separate backend and epia SP8000 front end. Having now tried out 8.04, ( posted here as I cant find a page on your site for 8.04), the backend is fine, but I think the front end is suffering from Xvmc not working for the epia board, despite choosing the appropriate settings making video playback impossible. Googling about it seems I am not alone, but have not been able to find a solution. Have you or anyone else had this problem?


  51. I’ve gone ahead and bookmarked http://parker1.co.uk/blog/?page_id=33 at Digg.com so my friends can see it too. I simply used ninth level down » MythTV on Ubuntu Gutsy as the entry title in my Digg.com bookmark, as I figured if it is good enough for you to title your blog post that, then you probably would like to see it bookmarked the same way. Your ROCK ninth level down » MythTV on Ubuntu Gutsy ! Thanks,http://www.PhillyInjuryLawyer.com
