I must admit, I didn't think of such a scenario. So for now, I think
your diseqc.conf is correct. Your switch seems to use the DiSEqC message
to select one of three LNBs while voltage and tone tell the LNB which of
the 4 bands it shall pass on to the cable.

To just prove my understanding:
Your VDR is able to switch to all three satelites, but from time to time
you get those tuning timeouts. Reloading the drivers fixes this issue
and VDR can then switch to all three satellites again.

Haven't had a look at this yet.
