Well, concerning the cables, my setup just misses the right 4 ones for
the 28.2E LNB.

Do you really have QUAD LNBs? I have QUATTRO LNBs.

The difference is, that a QUATTRO LNB supplies the 4 bands (Horizontal
Low, Vertical Low, Horizontal High and Vertical High) on specific ports
on its own, while a QUAD LNB needs voltage and tone signalling on each
port to decide which band it supplies to that port.

Would you mind providing some links to documentation about your LNB and
switch models?

Maybe it has to do with the QUAD - QUATTRO issue, but let me first have
a look into your documentation.

Hhm, these settings only help in determining high/low band and the
frequency to tune to. I first need to take a look into the code how
kaffeine and xine-lib pass the information about the port to use to the
DVB driver.
