Hello Scott,

I had the same issue a few weeks back.
The solution is to add a 0.0.0.0 0.0.0.0 mroute on R3 pointing to the IP of R2 frame relay interface and also enable PIM NBNA mode on R3's frame relay interface.

Here is the relevant config:

R3
ip multicast-routing

int ser1/0
ip pim sparse-mode
ip pim nbma-mode

ip pim rp-address 150.1.2.2
ip mroute 0.0.0.0 0.0.0.0 132.1.0.2

Although I still don't completely understand why this works Scott Morris suggested that the mroute allows R3 to send the join out the frame interface.
