Both of these channels are recorded via firewire. For a while I thought I was having a problem with any program recorded via firewire, but finally realized it was only those two channels. After racking my brain trying to think of anything that had changed in my setup, I remembered adding ivtc to my custom filter list. I turned on ""playback"" debugging, and sure enough, ivtc was being activated inappropriately. After removing ivtc, the stuttering has gone away. What is interesting about this, is that the stuttering may not usually happen right away. It can take up to 10 minutes before it starts. Once it starts, however, it does not go away. I am attaching a ""-v playback"" log. John " defect closed minor unknown mythtv 0.20 medium fixed ivtc filter stutter 0
