[MEncoder-users] Problem with .mov SVQ3 file (bug?)

[stoub at jeuxvideo.com]

Hello,

I'm trying to transcode a .mov file, encoded in SVQ3/MP4A. There seems 
to be a bug in last svn that wasn't there before, because it works with 
svn build 24537, and not with svn build 27081 (i'm using the win32 
builds I found here: http://oss.netfarm.it/mplayer-win32.php )

The last svn seems to detect a false framerate (1000 times too fast), 
here is the result of mplayer -identify on this file :
