I disagree, is a valid multicast IP/group address that can be used on IP
networks.  What led me to use this is that this is the multicast IP/group address I
told videolan server to send the data out to, and 1234 is the port #.  Xine and the
Videolan client both take this info as is and work, so I believe the information is
correct.  Multicast IP addresses fall in the Class D IP ranges as defined by the
IETF, and are 224.x.x.x-239.x.x.x.  Since I am doing this on a private net with no
routers, this should work fine.

See above....

See above.  I don't know that it supports "RTSP" but it does say that it uses RTP to
send the stream.  Other video streaming devices such as those from Vbrick systems
work in a similar fashion.
