"IGMP Snooping" or "Multicast Multilayer Switching" (MMLS) would probably do the trick but a quick look in the Software Advisor http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl?Introduction=True doesn't bode well for you. It doesn't look as if the 3550 supports either feature. You may require a higher end switch. I've implemented IGMP Snooping in 6509s, but nothing smaller. Without one of these features, which allow the switch to know who's interested, the default is to flood multicast. Maybe there is a L2 access list option or something?
