    10.10 won't record or play livetv

    As I was having a number of problems exporting recordings, I decided it was time to wipe and rebuild my backend. That went smoothly. I accepted all the defaults plus the closed source mp3 codec. I went through the configuration and got my three hauppauge cards set up (two PVR-150 and one PVRUSB2). All seems to be good. However, when I set some programs to record, I ended up with a 1K file with no thumbnail. Of course it does not play and also LiveTV does not work.

    You'll need to check the backend log for clues.

    Are all directories in your storage group set up properly and writeable by mythtv?

    No good trying to diagnose without logs.

    Sorry, as it was a fresh install, I thought this might be a common/known problem.

    Here is information on directory permissions:

    linghome@MYTHBUNTU-BACKEND:~$ ls -l /var/lib/mythtv
    total 40
    drwxrwsr-x 2 mythtv mythtv 4096 2011-02-08 17:03 banners

    mythtv linghome

    linghome is the user I created during the mythbuntu installation. I have attached my backend log. I have searched based on the errors (did that before I posted) but couldn't find anything useful. Thanks for any assistance.

    how did you set up the tuners in mythbackend? as a v4l device or a mpeg 2 device?

    Well, I suppose the first major error of the log is the one to try to track down first:

    "2011-02-06 21:37:22.311 MythBackend, Error: No valid capture cards are defined in the database."

    Which would seem to imply that the capture card section of the backend setup hasn't been properly completed.

    Nah, start at the bottom (newest log entries) and work backward. He isn't getting that error anymore.

    Code:
    2011-02-08 17:00:06.510 Error deleting 'GetPlaybackURL/UNABLE/TO/FIND/LOCAL/FILE/ON/MYTHBUNTU-BACKEND/1003_20110208170000.nuv' could not open 
    			eno: No such file or directory (2)
    2011-02-08 17:00:06.562 Delete Error 'GetPlaybackURL/UNABLE/TO/FIND/LOCAL/FILE/ON/MYTHBUNTU-BACKEND/1003_20110208170000.nuv'
    			eno: No such file or directory (2)
    How did you set your card up in mythtv-setup? You card is definitely set up incorrectly.

    Thanks. Yes, that is why I don't always like posting logs as someone will seize on a problem that was fixed two days ago. What about 'GetPlaybackURL/UNABLE/TO/FIND/LOCAL/FILE/ON/MYTHBUNTU-BACKEND/1003_20110208170000.nuv' tells you it is a problem with the card? I thought maybe it was a problem with a directory alias somewhere? I deleted my cards and re-added them. Maybe something is incorrect, but I have set up many (many) cards and I don't see it. Can you be more specific as to where I ought to look?

    They are all three (2 PVR-150 and 1 PVR-USB2) set up as V4L. I went back and deleted all of my capture cards and video source and re-added them. I set another 30 minute program to record. I don't think that will fix it as I have already tried that, but we'll see. Thanks.

    The .nuv part. PVR cards will record mpg files, you have set the cards up in incorrectly in mythtv-setup. They need to be set up as mpeg2 (ivtv) cards, not V4L.
