I've seen these errors occasionally, and think it may be a case where 
the machine was i/o bound and ivtv was generating data faster than Myth 
could record it to disk.  Sometimes the video is still watchable, 
although with lots of artifacts and occasional pauses.  The only real 
solution I've found is to schedule it for re-recording.

The first 4 characters of the filename are the channel ID.  You can look
up that channel in the mythconverg database using:

    select capturecard.cardid,videodevice,inputname from channel \
    join cardinput on cardinput.sourceid=channel.sourceid \
    join capturecard on capturecard.cardid=cardinput.cardid \
    where chanid=9999;

Substitute the channel ID from the filename in place of 9999, of course.
