[mythtv-users] audio/video stutter

[d.sailer at comcast.net]

dmesg seems to be pointing at a problem with using the kernels tveeprom & tuner. Are you sure you reloaded these modules after renaming them? (or maybe recompiled your kernel again after).  Another thing to double check is that you have the correct firmware for the cards.
