I haven't used MythTV seriously, but try a different audio driver (OSS vs. 
ALSA, for instance) if possible.  Also, bear in mind that if this "buffered 
audio" is a live stream from the net that's been compressed a lot, it by have 
inherent problems in how it was created, that aren't related to your system.
