The short answer we got from the manufacturer of the ASI-to-TSoIP converter is to configure for IP multicast.

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.
