hmm... what media player are you using to watch your videos? 

I've experienced similar to this issue with my ATI card watching movies
and listening to music through Totem (both gstreamer and xine backends,
but not in a xinerama setup), though it usually just came in the form of
distorted sound (sometimes skipping, sometimes it sounded like
chipmunks). My solution was to use VLC Media Player to watch my videos,
as this got rid of most/all of sound lag/stuttering and video
hesitation.
