Verify the multicast application can be routed. Many multicast application will default TTL (Time To Live) = 1 which invalidates any routing configuration as packets will not traverse more than one hop.

You can verify this behavior by taking a packet trace and examining the packet details.

From his discription of the network, the multicast traffic is being sourced from the server on vlan 4. If he is able to see the traffic on vlan 90 then the traffic is getting forwarded over one router hop.
