I had same problem before. I recommend you to enabl ip pim sparse-mode over
lopback0 in R2.
Plus this link will give you some information about multicast over
Frame-relay

Subject: Re: Multicast over FR
are you using static-RP or auto-RP? Is the frame-relay cloud one single
subnet? Are your Frame Relay mappings correct?
