I've done a little program using live.com RTP to stream a MPEG2-ES video file to a multicast address, similar to the test program that comes with that library testMPEG1or2VideoStreamer (I've checked with this program too). The stream is correct as MPlayer is able to play it with "mplayer rtp://239.255.42.42:8888".

This is because the rtp access module detects that it is a mpeg video es,
and tries to force the appropriate demux. Problem is that the demux was
renamed from "es" to "mpgv" some time ago, and the access module haven't
been updated apropriatly. This will be fixed in the next release. In the
mean time you can use a sdp file to make it play like Ross suggested.
