[MPlayer-users] [BUG] movie-aspect autodetection failes for mkv in r22325

[Andrew Savchenko]

Hi, all

In current SVN revision 22325, movie aspect ratio detection failes 
for matroska container (in spite of it works fine for avi). 

This feature works fine with r22290, so something was broken 
recently. Regression test shows that problem appears in r22295.

Here is mplayer's output for current svn head:
