[MPlayer-users] Windows MPlayer 1.0pre8-3.4.2 problem w/stuttering audio

[Robert La Ferla]

I am trying to play MPEG-PS videos but the audio isn't working  
properly.  After several seconds of normal playback, the audio will  
stutter.  It usually corrects itself after several seconds but then  
it does it again and again.  I am using Windows XP on a Shuttle  
SN41G2 PC.
