	I call these packets transcendental - they come "from

	Yes.  Rev level D (downlevel from the rev E bridges you have
	that are giving you grief) do not have the problem, and respond
	correctly when RBMS asks them if they have "registered" a
	multicast address.  Rev level F also do not have the problem,
	but they also do not like being asked if they have registered a
	multicast address.

	Please contact me if I can be of further help...
