That's a different problem. wmv over rtsp is not implemented yet
Even worse: WMV over RTSP is not even *defined* yet - at least, not in any document that I've been able to find. Running "openRTSP" on the "rtsp://" URL above reveals that the stream uses three 'experimental' RTP payload formats: "audio/X-ASF-PF", "application/X-WMS-RTX", "video/X-ASF-PF". However, I don't know anything about these payload formats; they seem to be Microsoft-specific crap. Ross Finlayson LIVE.COM <http://www.live.com/>

hmm, this cant be good. thank you for the info. another sample stream: rtsp://195.219.160.200/mcp?chid=25&pid=196&vid=2402201&br=800&tid=1&void=2844&muk=H1J4yFr0mJB this time the http trick does not work. it reports: Failed to initiate "audio/X-ASF-PF" RTP subsession: RTP payload format unknown or not supported Failed to initiate "video/X-ASF-PF" RTP subsession: RTP payload format unknown or not supported from: http://player.narrowstep.tv/nsp.aspx?player=F1R&void=2844

this time the http trick does not work.
it reports: Failed to initiate "audio/X-ASF-PF" RTP subsession: RTP payload format unknown or not supported Failed to initiate "video/X-ASF-PF" RTP subsession: RTP payload format unknown or not supported from: http://player.narrowstep.tv/nsp.aspx?player=F1R&void=2844
VLC has implemented support for this wicked format. Go and steal it ;-) After quick testing, it seems like VLC 0.7.2 is now not working with M$' "RTSP" protocol (it used to work, but it broke down somehow). Tough luck. Don't you just love M$? Regards, Shachar, who's Uni. force him to use this protocol to see his video lectures.

http://p084.ezboard.com/fstreemeboxvcrfrm10.showMessage?topicID=142.topic says that on some of these servers you can switch rtsp to mms, should this be default for rtsp://wmv in mplayer? mms://195.219.160.200/mcp?chid=25&pid=196&vid=2402201&br=800&tid=1&void=2844&muk=H1J4yFr0mJB works. for more information see: http://p084.ezboard.com/fstreemeboxvcrfrm7.showMessage?topicID=51.topic which describes and links to msdn article on correct order of protocol rollback.
