Filtering Multicast Traffic

I've got a handful of PowerConnect switches on our network and am experiencing major slowness as a result of our IP security cameras that talk to our phone system.  I moved them off onto their own Vlan, but when our 3524P switch is connected to our 6224 (routing) switch, ping response times between networks go way up and sometimes fail. (And if I disconnect the uplink from the 3524P they go back to normal)  I've tried to setup mulitcast filtering, but that hasn't seemed to help.  Does anyone have any ideas that I can try to fix this?  I basically just want the multicast traffic to stay on the 3524P switch, but still have connectivity from the other networks to be able to talk to the .130 network.  Thanks in advance for any help you can give.
