Hi David
you are missing some config,
ip pim bsr-candidate *type number* *hash-mask-length* [*priority*]
for the bootstrap router (R1 in your case).
also in hub and spoke you want only the hub to be the RP and not one of the
spokes!
also you do not need to set ip pim sparse-dense mode a ip pim sparse is
enough.
you can read this
http://www.netcraftsmen.net/welcher/papers/multicast04.html
or http://cciep3.blogspot.com/2007/10/ccie-pim-auto-rp.html although this is
explaining AutoRP it will give you some ground for Multicast.
