[c-nsp] VC Multicast Issue

So I'm running into this interesting problem (well it's interesting
for me at least…) I'm running a vc (70) between 2 7507's, on each end
is a 5500 switch (5509 on the Router 1 side, 5505 on the Router 2 side
not that it should really matter). The vc comes up fine and I can
ping/ssh/whatever across the line fine, however there are multiple
multicast sources present at the Router 2 location that don't make it
back to the Router 1 location. Strange thing is that I'm seeing the
PIM make it across the wire, but nothing of the other multicast data
does. I've played around with all of the settings, rebuilt the vc, and
have even tried it on a different set of routers running 12.4, but
still get the same results. Any thoughts? This one really has me
scratching my head (maybe I've been looking at it too long.)
Thanks,
Jayson
