Yes, I prefer to be able to watch the windows media content (application/x-mplayer2) in mplayer standalone. I am able to do this with some channels, but most of the channels don't work this way. For instance http://www.utv.bg/tv/stream.php?code...ksDJ26yGhfdF4e says launching mplayer playlist, but nothing happens. I don't get any error message to understand whether the stream is not working/server is down or mplayer is unable to play such content.

I am running dbus-switchboard 1.1.2.
I checked
/usr/lib/application/defaults.list,
/home/user/.dbus-switch-xref.cfg, and
/home/user/.dbus-switch-apps.cfg files, but I am not sure where and how to put the association of application/x-mplayer2 with mplayer.
