Multiple WMV tracks
This bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=496291 includes a file with three identical WMV video tracks of different encoding quality.
It is not clear to me that showing all three videos by default is correct. VLC should probably pick the highest quality, if the informations in conveyed in the container. Feel free to close this invalid/wontfix as appropriate.
