Thanks Ross. You have been of great help. 
I have followed your advice and have used the RTSP Server from live.com...
I have a camera pouring out udp encapsulated mpeg2 data which my program after 
RTSP session establishment forwrds to VLC player.
I am planning to build an RTP packetizer so that VLC player can accept the 
data. However I wanted to know that if I wanted to use "your" RTP packetizer. 
How would I go about it. I have a fair idea of RTPSink (files) and stuff from 
the code Server code.
Thanks a lot.
Moses.
