The last step was simple; I had misconfigured the card's default input, which should be set to "Tuner 0" instead of "Composite 0".

I found a page at http://mythtv.info/moin.cgi/XmlTv/MythChannelSetup that got me thinking. In mythsetup I opened the Channel editor, and changed the freqid field to the frequency numbers instead of the short PAL europe-west aliases. In MySQL, it now looks like this: mysql> select chanid,channum,freqid,name from channel order by chanid; ++-++---+ | chanid | channum | freqid | name | ++-++---+ | 1 | 1 | 287250 | NRK 1 | | 2 | 2 | 196250 | NRK 2 | | 3 | 3 | 210250 | TV 2 | | 4 | 4 | 231250 | TVNorge | | 6 | 6 | 259250 | TV 3 | | 7 | 7 | 266250 | TV4 | | 8 | 8 | 189250 | SVT 1 | | 9 | 9 | 217250 | SVT 2 | | 10 | 10 | 154250 | Discovery Channel | | 14 | 14 | 252250 | Disney| | 15 | 15 | 294250 | BBC World | | 17 | 17 | 280250 | Eurosport | | 18 | 18 | 161250 | Animal Planet | ++-++---+ 13 rows in set (0.00 sec) Now, mythbackend doesn't report any failures at all.

Re: [mythtv-users] LiveTV bails out after two seconds
It still seems like mythtvsetup isn't setup properly, and I keep wanting to come back to it. I too had a similar problem with this because of how MythTVSetup works. The tuner must first be setup in the Input settings Second, your cable type must be setup in the Video Sources screen Finally, you have to link the two settings together in the Input Settings. In the input settings, you can select the input type (Cable, Antenna, DVB, etc) and then when you link the settings together in the Input Settings, you should select the same type. If you aren't able to figure it out, I should be able to help you further when I get home from work... most of this is coming off the top of my head ATM. More information can be found here regarding this. http://www.mythtv.org/docs/mythtv-HOWTO-9.html You can also check your channel settings there. Let me know! Good luck! -James -- James D.

It looks like you ran mythsetup as root, you'll need to rerun it as your myth user. Setup your tuner settings for your input card. Also, I would try setting it so that your video directory (I'm guessing /var/video) has read/write access for your user. Give that a shot.

Re: [mythtv-users] LiveTV bails out after two seconds
I had a similar problem with my MythBox... however I don't know if the situation is similar. My box was able to view live TV after doing the initial run of mythbackend and frontend run as the *user*, however when I set everything up to startup automatically, I would get the same two-second error with LiveTV. Tore my hair out... and so two things have come out of it. 1) I'm bald. 2) Even better, I found a solution. What I ended up doing was actually starting mythbackend and mythfrontend as the user who was going to access the system (mythuser in my case), and I no longer loss LiveTV ability. The socket problem *I believe* is related to the fact that the system is attempting to access the capture device and does not have accesss to it. As far as I know, solutions to this would be to run mythfrontend as SUID root or to run the frontend/backed as the user. I don't know if this is a catchall, but try it out and let me know if it works for you. Good luck! -James -- James D.

I have eliminated a couple of problems: > 2005-07-29 12:01:28.711 Realtime priority would require SUID as root.

I tried glxgears, and lo and behold, it displayed exactly the same error.

[mythtv-users] LiveTV bails out after two seconds
