Oops - you're right.  And *that's* your problem!  The IP address in a 
"rtsp://" URL must be a *unicast* IP address - the IP address of the 
server.  Note that RTSP uses TCP, which is why it needs to use a unicast 

Just use

I suspect that it *doesn't* use RTSP.  If not, then you'll need to create a 
SDP file, and use MPlayer's "sdp://" pseudo-url - i.e.

The SDP file should look something like the following:

s=Test MPEG-2 TS session
t=0 0
m=video 1234 RTP/AVP 33
c=IN IP4

Note the "33", which is the static RTP payload format for MPEG-2 Transport 
Streams, "", which is the session's multicast address, and "1234" 
which is the session's (multicast) port number.

I hope this works.
