[MPlayer-users] DXR3 audio/video sync issues

[William R Sowerbutts]

For what it's worth, Xine plays these files perfectly on exactly the same
hardware. I think Xine takes the DXR3 card's SCR clock into account in some
way.

Anyone want to fix this in mplayer? Support for seeking (essential for advert
skipping!) in Xine on the DXR3 kinda sucks.

Thanks,

Will
