A pair of NetGear GS752TXS switches.
They do have an IGMP querier feature, but AFAIK it is only active when 
you've configured them as the router (layer 3 functions), and I'm only 
using them as layer 2 devices because the L3 implementation is, um, not 
useful.  IGMP snooping works properly in L2 mode regardless.

The router/firewall is pfSense, which does IGMP proxying, but apparently 
not querying... or at least not correctly :-/.
