I suspect that he may have misunderstood your question. You were (I
presume) asking if multicast RTP sessions could be played, using RTSP for
session control. However, he might have thought that you were asking if
RTSP itself could use multicast - which, of course, it can't, because RTSP
runs over TCP.

If the box uses RTSP for session control, and also supports multicast, then
I would assume that it can play multicast RTP sessions. But of course
you'll need to contact the company to be sure. (Who knows - maybe the box
uses the LIVE.COM code also :-)
Please let us know what you find out.
