audio not in sync w/ video

[silguy]

I got a few rips that the audio does not quite sync w/ the video on the PBO, anyone experience this? It does the same thing when I'm using my computer's media player classic. But, when I use the regular media player, it's fine.

The rips are mp4 files and comes in 2 ch or 6 ch options. This "unsync" happens when I try to embed the 2ch or the 6ch using YAMB software.

Any suggestions to play this smoothly on the PBO?



Thanks,
