I am experiencing a problem with my multicast music-on-hold streams. It seems that all streams are sent to my branches and I am not sure why.
I am running sparse-dense pim.
I look in the IGMP group memberships and none of my moh streams are registered.
So I assume that the routers themselves must be notifying the DR that they want the MOH streams.
So I can tell and how can I prevent the routers from requesting unneeded streams?

In CCM you may configure the MAX HOPS for MMOH in MOH server configuration.
Or create an ACL and multicast boundary in your WAN interfaces.
The following is an example configuration:
Router(config)# interface serial 0/0
Router(config-if)# ip multicast boundary 1
Router(config-if)# exit
Router(config)# access-list 1 deny 239.1.1.1

Brian,
Does a show ip mroute count confirm that the multicast streams are being forwarded by the routers?
I have never seen this happen with sparse mode PIM, so unless you really need sparse-dense this might be another solution in addition to those suggested by Gonzalo.
Here is a good document for troubleshooting multicast issues:
