I'm a big fan of VLC for testing multicasting:- http://www.videolan.org/vlc/
VLC is a media player, voice of video and it will stream to a network
destination, unicast or multicast - it's free too.
Put one copy on a pc and stream some music or video out to a multicast
address, then put another copy on another pc and subscribe to the
stream. Then you can alter the rate limiting in the network and
watch/listen to the impact. It's also interesting to pull links and see
how the PIM reacts.
