Given that it runs for several hours sometimes with no issues it would seem odd it would be a disk IO problem. The buffer pretty much just sits there full until I start to see problems, and no amount of stopping the video resolves the problem. Pause will refill the buffer, but once unpaused it almost instantly empties. Once it's stuttering it doesn't recover. (at least over intervals of a half hour or so, which should clearly resolve a buffering problem. The system is WD Green Caviar drives, non-RAIDed. One single drive is used exclusively for Myth. I get no SMART issues, or errors in /var/log/messages. If you have pointers for debug beyond what I've posted so far I'd appreciate any insights.
