Hmm, does this mean, you will not implement this handshaking into the LIVE.COM 
libs?
If not surely some mplayer developer will develop RTSP code that is able to do 
proper handshaking with real servers and in this relation it's questionable 
if it's woth to invest the work to integrate LIVE.COM lib with MPlayer now.

What do you think Ross? What other benefits would LIVE.COM give, that would 
benefit MPlayer in case it had an own RTSP implementation?
What - besides possible law problems - speaks against integarting real rtsp 
handshaking into LIVE.COM libs?

Btw. as MPlayer is mainly developed in hungary, we are probably pretty 
resistant against lawsuits by realmedia :)

Also I don't quite understand how they could sue you for talking to their 
servers, after all they don't have a license agreement on every website that 
you have to agree you that includes a clause that you may only use original 
RealPlayer to stream from their servers.
