[mythtv-users] Audio Synch problems in Myth-10?

[John P DeVale]

I traced my problem to insufficient CPU.  Either the myth process became 
heavier in the .9 -> .10 release, or I futzed with a setting and don't 
remember.  Now 480x480 MPEG4 is just a bit too CPU intensive for the 
1GHz PIII with both the HQ button things selected.  Backing off fixed my 
problem.  I have compiled the codec library with the latest optimizing 
compiler from Intel (v7), and will do some tests tonight to see if I can 
get some of the performance back.
