Partially wrong. For multicast You need to select as mcast-addr adress in
range 224.0.0.0-239.255.255.255. Adresses in 224.0.0.0-225.0.0.0 can be
assigned only if You have network without routers. Reserved addresses are
described in RFC, or you can read this article:
http://www.linuxfocus.org/English/January2001/article144.shtml

So if you stream to mcast you should set as output URL something like this:
{acodec=mp3, vcodec=WMV2,mux=asf,url=225.0.0.1:1234}

So on the player you should open stream as: mms://225.0.0.1:1234
Check, if on both sides is mcast-routing is set for network 224.0.0.0/4 on
the interface, which is envolved in multicast.
