[mythtv] Audio problem when changing channels

[Randy Page]

I seem to have an audio problem when I change channels quickly using mythtv.  
After about 4 channels the audio starts to slow down. After about 6 channels 
iiitttt iisss sssooo sssloowwww. I thought I was changing too quickly, and 
that maybe it would catch up, but no dice.  

Anyone else seen this?
