[mythtv-users] how do I stop prebuffing problems with audio

[Paul]

I'm frequency seeing the following messages and getting audio slightly 
out of sync with Video

2008-08-31 11:52:36.618 NVP::AddAudioData():p1: Audio buffer overflow, 
audio data lost!
2008-08-31 13:01:11.653 NVP::AddAudioData():p1: Audio buffer overflow, 
audio data lost!
2008-08-31 13:07:36.404 NVP: prebuffering pause
2008-08-31 13:15:46.553 NVP::AddAudioData():p1: Audio buffer overflow, 
audio data lost!


I'm using DVI-> HDMI output to a HDTV using HD1080i
I'm running FC8 with Nvidia rpms using a VGA=NV 6200 GT and CPU=AMD 3200+

My CPU doesn't seem to to be a problem ie it sits around 30-50%
