Multicast on 3750s

I see that cgmp is not supported on Cat3750s. In other catalysts I just enabled cgmp to be sure that a multicast stream did not get forwarded to every port on the switch. What do I need to configure on the 3750 to accomplish the same end? I don't play on having any inter-vlan multicast. Just need to know how to control it within a single vlan. Thanks.

Enable IGMP snooping (believe the 3750s support it).
