Not intentionally, it attempts to select the highest-quality ones,
but plays whatever the server sends.
So it is probably the usually issue of the server somehow
misunderstanding our request and sending the wrong versions.
I think we never figured out how to avoid this.

They might both be too old, but for MPlayer compiled from latest SVN at
least I can get the higher quality versions by using
ffmpeg://mmst://195.94.205.211/Trwam
instead, so at least for this server the FFmpeg implementation of MMS
works better.
