[Bo Xie]

http://ffmpeg.sourceforge.net/ffmpeg-bugreport.html says I should post
bug to devel ML,not user ML. Then here it is and hope there is some
guy to care it. Thank you!

I use the following steps to repeat the bug.

1.Download FFMpeg-20050508.tar.bz2 (the latest cvs)
2.Compile it with cygwin 1.5.13.
3.Run it with the following log (c:\a.asf is 01:02:11 time length, and
mplayer can player it and seek it well):

If you want more info (eg. let me upload the c:\a.asf file),please let
