Yes, of course.  Without a SDP description for the stream, how could 
QuickTime Player (or any media player) possibly know:
- What multicast address is being used?
- What port number is being used?
- What RTP payload format (i.e., codec) is being used?

A media player needs a SDP description for the stream before it can play 
it.  As I said before, the best way to get the SDP description is using 
RTSP (by opening a "rtsp://" URL).
