I think the switch just does not care, passes satellite signal with every
other signal to DVB card, and on the way out pick-ups the diseqc signals
too. Very much I have no other explanation. These switches are very small
and not very sophisticated.

If those switches got some sort of "address" I have no idea how to find it,
I don't even see any commands that would help to do it. I'm trying to figure
out how to do basic diseqc stuff right now. This table of commands seems to
have an option to read "slave address":

I'm not sure what that is but I would guess its probably current used port
address. If its possible then Id guess we should be able to use third party
diseqc tool to read "addresses" and then set them up for VDR before VDR
starts. I wish there was good diseqc how-to some where.

"clean" multiswitch idea is good but more expensive :) I guess I'll have to
look at it if I won't solve "broken" one. I'm looking through options right
now.
