Audio/Video sync

[Anuj Khanna]

Hi all,
I am rendering a video in managed DirectX, using vmr9 and custom
allocator.
Problem is audio/video are not in synchronization. I had also checked
file in other players with no problem.

My findings: when i seek the position backward or forward solve the
problem.

Hack that i found solve problem in some files but not for all. I had
called WaitForCompletion() after run() on graph with timeOut of 100ms.

I dont have any idea why a/v sync slip from track.

Anyone know what going in there and have any idea plz share. Or
anything i missed.

Thanks in advance.
