Multicasting Help needed

Dear Experts,

I have 4 6509E cores switches. One pair running VSS without VRF, it is linked to another pair (running VRF with ACE and FWSM running) via PortChannel. This port channel is simulated as WAN link between both pairs of switches running OSPF.  All separated by VLANs.

Im trying to perform a multicast streaming from btw this two pairs of core switches, but it does not seems to work. I did enable ip multicast-routing vrf <name> and ip multicast-routing.

What else do I need to do to allow this multicast streaming to work across them? Please advise me.
