Multicast and VPNs

Hi my fellow networking friends. I am fairly new to this field, and very new to anything using multicast. However we have two servers using multicast across a customer provided network. Our vendor states not all of the multicast traffic is getting through, and that the customer is blocking this somewhere. Our customer claims they are not blocking anything.

When we put in a VPN tunnel between the connection, everything flows through just fine. When we remove it, it fails.

Is it possible multicast would require a VPN over a point to point connection? Thanks in advance
