thanks to all who replied, I got it to work. I forgot to put ip rp-address
in R5. I originally had it in R3 and set R2 to be the RP point but forgot
to put it in R5. I did not think it was needed so I took it out since it
wasn't working anyway. The final working configurations is as follows. (
Looks like I've to go back and review multicasting more)

Subject: RE: ip multicast over frame-relay configs
Tin,
When you use sparse mode only you have to an RP for the network. I
don't
see any RP config in your routers nor static neither auto-RP. My advise is
to make sure you understand the basics of multicast routing and PIM before
attempting to configure it. It will be much easier for you and you'll be
able to understand what is going on!
Also the "ip igmp join-group" command is something that you normally
configure on the end segments of the network, like an ethernet where the
users should connect to. It's good to simulate a user sending igmp join msgs
for an specific address. Remember that IGMP works between the end stations
and the router.
Finally, if your FR is a full mesh, you don't need to use "ip pim
nbma".
Take care,
FM
