contains asx playlists. eventually it ends at a real mms:// uri like:

mms://videoserver.tilde.ee/Console/seitse210306.wmv

which gives:

** Message: don't know how to handle video/x-wmv, wmvversion=(int)3, framerate=(fraction)10000000/333667, width=(int)320, height=(int)240, bitrate=(int)210806, codec_data=(buffer)4e391a01

for which I don't have a plugin yet. Audio plays fine.

I get the same "Only a subtitle stream was detected. Either you are loading
a subtitle file or some other type of text file, or the media file was not
recognized." error here. I'm not sure what it means.

It means we got an .asx playlist (which will be recognised as text/plain, which decodebin thinks is a subtitle file on its own without a movie stream). Not sure if the fault is with totem or not.

Totem mozilla viewer bug (doesn't parse playlists).
