I am by no means knowledgeable in this area but to guess it sounds to me like you need a third device to route traffic between VLANs. Additionally, just to use PIM or DVMRP on your 3750 you need to verify you are running the IP Services image.
You know what they say about free advice...

| Hello Trilug,
| I am having trouble piecing together multicasting between two 3750G
| switches. Here is my situation:
| I don't have control over switch 1. I have control over switch 2.
| Switch 1 has vlan 1 with multicast traffic. Switch 2 has vlan 2.
| Switch 1
| and Switch 2 do not have a trunking protocol between them.
| I would like to connect the switches with access ports and have switch
| listen for the multicast traffic from switch 1:vlan 1, then use the
| capability of the switch to route the multicast traffic to the
| access ports of switch 2 that are on vlan 2.
| I know I am asking to do a hackish thing without a trunk and if you
| read this far I appreciate your attention to this off-topic subject.
| respect the broad range of knowledge that this group holds and hope
| can tell me: "Hey, dummy! This has to be done at the router with
| or "Sure, try this..." I am fairly certain that the access port must
| "subscribe" to a specific multicast feed which will throw my idea out
| window anyway.
