[SBE] Questions about IP multicasting

Working for a small independent TV station that is trying to set up an STL
using TSoIP.  The catch is, they need to feed two separate devices at their
tower site with the same TSoIP stream.  The short answer we got from the
manufacturer of the ASI-to-TSoIP converter is to configure for IP multicast.

I did a rudimentary test with an ASI-to-TSoIP converter going to an
ethernet switch and feeding a stream to a corresponding TSoIP-to-ASI
converter and to a Sencore decoder with a TSoIP receiver card.  Naturally,
that worked because all equipment was connected to the same physical
switch.  But, now that I've moved the "receive" end to the transmitter
site, I'm having a heap of trouble getting it to work.

Searching the web for all things multicast, I'm finding that this is easier
said than done.  Has anyone out there in TV Land had any luck with what I'm
trying to do?
