Can you report a bug about this at http://bugzilla.gnome.org and also
include a GStreamer debug log from the sender side with GST_DEBUG=udp*:6
while running with GStreamer 1.2.3?

Versions before 1.2 had known problems with multicast and UDP in general
on Windows, so it's not surprising that they don't work. 1.2.3 is
supposed to work though.
