I did not try all three of the switches but only two
when I connected directly the switch. I still could
them to work. I also forgot to mention that on this
computer I also have Windoz and there it always
worked. Don't know though how MyTheatre does the
switching (and don't care as long as Linux is OK).
One thing that I,ve seen about the Twinhan cards is
that they tend to generate noise with the diseqc
commands. Perhaps the noise is masking the diseqc and
switches cannot filter them. At the same time Spaun
switch is supposed to be very good at that. Also I am
sure there are a lot of people out there which use
similar cards and I do not see similar reports.
