Probably requires WMV codecs?

Edit:

  sudo apt-get install gstreamer0.10-plugins-ugly gstreamer0.10-plugins-bad gstreamer0.10-ffmpeg

Don't let the names scare you, they refer to the licenses not the quality of the code. Normally these would be detected and installed automatically, but there's a bug that prevents mms:// content from being autodetected.

edit2: fixed codecs, sorry
