If you're using release version 0.21, upgrade to the latest 0.21-fixes.  
There were quite a few audio-related fixes.  Also, there's likely to be 
additional fixes added as more testing occurs.  Most likely the audio 
issues you're seeing (if they are causing your performance issues) have 
nothing to do with the playback profiles since they do not affect audio 
processing.

No, but you must have MythVideo videos in mind when designing your 
playback profile group.

Basically, choosing Slim is the equivalent of the 0.20 software rendered 
output (no XvMC, no PVR-350 output).  Try that and see if it works 
better.  If you lost your defaults, see
