That is specified in another RFC handling MPEG TS encapsulation in RTP. 
I can't remember the exact RFC number, but if you search for all RTP 
stuff in the index then you will find it. Correct me if I'm mistaken but 
VLC will do MPEG ES over RTP too these days (starting v0.7.0 test1) 
using livedotcom library.

Tell them to listen to the streaming port using RTP ;-) Sorry cannot 
help you with an exact syntax.

Note that VLC also runs on windows. Using the RTP plugin would do it then.
