I've took a look at wireshark in windows, there were two problems: 1) The referrer field is sent from WMP. I don't think it's being send from linux. I'm pretty sure that there's some settings in the streaming server that restricts streaming to people with the right referrer only.
2) The protocol itself is not the standard MMS protocol. mplayer tries to use some kind of MMS handshake, while WMP is sending RTSP commands. I don't understand it, it seems to me that the MMS protocol is a propriety replacement to RTSP. If there's a video expert in the crowd, I can send him the pcap, I'll be glad for some help. However I believe that convincing mplayer to play the stream should not be that hard. All the information should be availible once you login, and I can write a script that given a video page at video.tau.ac.il gives the correct command line parameters to convince mplayer to send it. (BTW my friend will contact the helpdesk as soon as he'll finish some more urgent matters, I'll report here what did we achieve).
