playback (I'm assuming this is still the case). In order to support
mutlicast, '<FONT face="Times New Roman"

integrated/started to allow the running RTSP Server to perform mutlicast
playback. Is this correct or has multicast support been incorporated into
an RTSP Server?</FONT></FONT></SPAN></FONT></FONT></FONT></SPAN></DIV>

software support the RFC's 2326's multicast example
(below)? If it does would it be able to handle having the client set the
multicast IP destination & port in the setup command? Is there a
client already available that supports having the client setup
the multicast destination & port instead of having them determined by
the server? </SPAN></FONT></FONT></FONT></SPAN></DIV>
