Comment (by batou):

 @cehoyos: I have no idea how old that WMV file is but I've been unable to
 play _any_ WMV3/VC-1 video with mpv recently. mpv produces visual errors
 on all of the files I tried even though other players play them fine. It
 only happens with VC-1/wmv3 files (other forms on .wmv don't produce
 visual artifacts with mpv). It's really annoying to have to use some other
 player.
