Hi--

I have a wmv3/wmav2 file that has sync issues in ffplay.

I've uploaded it to MPlayer/incoming/WMVSyncError, with the following  
description:

This file shows a sync error in playback.  It's using WMV3 and WMAV2.

It plays fine in QuickTime, VLC, and WMP.

If i open it in QuickTime, and export (using Flip4Mac) a smaller  
portion of the file, it appears to stay in sync.
The only thing different between the two files is the order of the  
streams, and that the exported version from
QT has a higher bitrate.

This version: (before dd'ing it)
Duration: 00:28:30.6, start: 3.064000, bitrate: 322 kb/s
Stream #0.0: Video: wmv3, yuv420p, 448x336, 30.00 fps(r)
Stream #0.1: Audio: wmav2, 44100 Hz, stereo, 31 kb/s

This file plays correctly, which was the above file, clipped and  
reexported:
Duration: 00:00:29.9, start: 5.000000, bitrate: 698 kb/s
Stream #0.0: Audio: wmav2, 44100 Hz, stereo, 64 kb/s
Stream #0.1: Video: wmv3, yuv420p, 448x336, 30.00 fps(r)

Any help would be appreciated!

Thanks!
