sound problem
 

i just started using bsplayer. i have a movie that is 2 files..one video ( avi. file) and audio( ac3. file). They start playing ok..after about 30 seconds, the sound starts to slightly slow down and you see the mouth move and hear the sound slightly after. How can i keep the audio and video in sync..

A friend told me i just need to change a setting but went overseas before he could tell me.. Does any one know what setting i need to change
