Hi,
Unfortunately I can't provide a solution however I have been having the same
error for some time now (multiple versions of ivtv anyways), it always
occurs when whatching Live Tv or a recorded program, thought a little more
info from my setup might help.
The playback freezes and looking at /var/log/messages has the error you
describe below.

Sometimes seems to coincide with the following in my mythfrontend.log

and this in mythbackend.log

Skipping back will often unfreeze the picture an allow playback to continue,
although I have noticed the audio getting out of sync after this.
I've spent a long time searching archives and have tried a few things. Any
suggestions/solutions would be great as this is the only issue I have with
an otherwise great system.

PVR350
Fedora Core 3 2.6.11-1.27_FC3smp
