In a configuration like the one you have described, where one LNB is
connected to two DiSEqC switches, apparently the signals sent to one switch
are propagated to the other switch via the LNB. What puzzles me is why
a switch would even listen to DiSEqC commands at its LNB _input_ - I would
think that it whould only listen to such commands at its receiver _output_.

Well, apparently they _are_ both always listening.
Do these switches have any kind of "address" that can be set individually?
IMHO that would be a first requirement if separate DiSEqC definitions per
DVB card should even have a chance to work.

At any rate, a "clean" multiswitch setup seems a lot better to me ;-)
