[mythtv-users] Myth freezes after kernel/ivtv upgrade - ivtv works fine

[Mark Knecht]

Hi,
   One of my mythbackend servers, up and running Gentoo and using a
PVR-150 for over a year, went through an upgrade cycle recently. It
has a new 2.6.15-gentoo-r1 kernel and the latest version of ivtv from
portage. Everything builds correctly and mythfrontend is able to play
videos that are already recorded. However if I try to record anything
new I get nothing and if I try to watch TV I get the typical 1 second
of TV and then it freezes. In dmesg I see these messages:

ivtv0: All encoder MPEG stream buffers are full. Dropping data.
ivtv0: Cause: the application is not reading fast enough.
ivtv0: All encoder MPEG stream buffers are full. Dropping data.
ivtv0: Cause: the application is not reading fast enough.

   I've already tried the thing where you delete your cards in
mythsetup and make a new card with new connections but that didn't
help.

   Is there something else I can try? Very soon I'm likely to try
rebuilding all of the major Mythtv components.

   I am able to cat the output of the ivtv driver into a file and play
it fine using these commands:

cat /dev/v4l/video0 >test.mpg
mplayer test.mpg

so it appears to be strictly a MythTV problem and not an ivtv or kernel issue.

   Because we have a number of remote frontend machines this system is
still running mythtv-0.18 and I'd prefer not to try upgrading to 0.19
as it's likely to take too much time.

   I'm here visiting for one more day so I need to solve this tonight
or tomorrow at the latest, so thanks in advance for any help you can
give.

Cheers,
Mark
