For multicast on a Cisco, you need the IP Plus version of Cisco IOS -- do
you have that? 

Once you have IP Plus, there are only a few command lines needed for the
router config.

The one "gotcha" at the server end is you need to adjust TTL (time to live).
The VLC default is something like 0 -- just increase that to, say, 12
(Overkill going through only a pair of routers, but it's what was in the
documentation somewhere, and it works fine)

(we just enabled VLC multicast through a pair of 1700-series routers 3 weeks
ago -- works OK)

To be able to forward multicast traffic across two interfaces you should
enable multicast routing protocol on both interfaces. On cisco you have
choice between old DVRMP protocol, PIM Sparse-mode or pim dense-mode.

This is best to enable pim sparse mode.
