I turned that preview off, but my watch recordings still stutters. I
think they did fix that issue. To answer your questions- I've got a
PVR-250, and most of the CPU was going to X.
Interestingly, I was wrong about the cause of the stuttering- for watch
recordings at least. High CPU usage WAS causing stuttering in Live TV,
but I have since remove some other running programs to get my total
mythfrontend CPU usage down to around 70% while watching LiveTV. Now
there is no stuttering when watching Live TV.
But Watch Recordings is still stuttering horribly, even though my CPU
load is only about 40-50% during it. Watch recordings is simply
unusable for me at this point. I have to use mplayer or totem to watch
those recorded nuvs. Maybe it's starved for data or something?
