Thanks Simon and James. Could I say with a good degree of certainty that
new switches from D-Link and TPLink would support it. I cannot find any
to say if they would or wouldn't.
The "blurb" about this system says that commonly used ethernet network
components can be used. However I am at a standoff with the support
engineer who is adamant that there is a network problem and therefore
cannot support this new piece of kit that has only just reached the UK.
I somehow have to convince him that it should be referred to the
developers. If it is not still underdevelopment why did the website
suddenly duplicate itself in Spanish? last week.
Thanks again for your help.

I have a problem with a new, complex system for managing ethernet

multicasts from a BT home hub.
For anybody that has followed what I have been trying to describe, do
BT Home hubs support IGMP? is there something in the configuration
that enables/disables it and is there a test that I can do to verify it?
The BT Home Hubs 3, 4 and 5 definitely support IGMP - BT Youview
requires it.
When the old BT freeview service stopped and I was "upgraded" to
YouView, I had to get a Home Hub 4 installed to replace my solid
reliable Netgear DG384 which didn't support IGMP (as far as I could
tell). My old Homehub 1 (once I'd retrieved it from its hiding place
in the loft) didn't work either.
There's a fairly old list of routers which support IGMP (and hence BT
YouView) at
