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.

Hello all,
My Myth box, specs below, has been in safe production (the old Replay
TV is not yet unplugged) for about two weeks now. Over the weekend, it
became unresponsive to remote and I could not get in via Mythweb. SSH
was sluggish but I could get in. Restarting gave me the 'GDM could not
write to your authorization file error, and executing 'df -h' showed
that my hda / partition was 100% full.
I traced the culprit to /var/log/syslog, which was almost 700MB.
Roughly 99% of it was the following, repeating and very frequent judging
from the timestamps:
mythtv kernel: ivtv: DEC: Decoder wants 0x0001 bytes, bad memory
location 0x0001.
mythtv kernel ivtv: DEC: Decoder wants 0x0001.
The above lines repeat anywhere from eight to twelve times, sometimes
the shorter line will appear twice, sometimes the longer line within the
repeating block, then the following might appear, and then they repeat
some more:
mythtv kernel ivtv: DEC: Decoder w01.
I'm going to post this to the ivtv list as well, but y'all are pretty
smart people and so I thought I'd ask you as well. Thanks for any
suggestions/ideas you can offer!
