[mythtv-users] problems with choppy playback and freezes

[David Barr]

I'm running mythbackend on a 1.2Ghz Athlon with a PVR-250 encoder card.  
Mythfrontend is running on the mythtv-xbox distribution version 0.4.5-beta.

I have problems with choppy sound and video that usually happens during 
dark scenes.  It happens both on live tv and recordings.  I've tried 
various versions of the IVTV driver and encoding rates.  This has been a 
problem on Mythtv version 0.16 and 0.17 (maybe earlier, too).  How can I 
fix this?

A more serious problem has appeared since I upgraded to 0.17.  If I'm 
browsing through the program guide with live TV in the upper corner of 
the screen, the frontend will frequently lock up.  I have to power the 
frontend off to recover, and I can't watch live TV until I restart the 
backend (all inputs in use error).  Has anyone else experienced this 
problem?

Thanks,

David
