I don't think that mixing V/H and R/L on the same satellite
is done - or is it?

In nit.c the polarization will be set to h, v, r, or l, depending
on the data broadcast for a particular transponder. The data in
diseqc.conf has to use H/V or R/L correspondingly.

# slof:           switch frequency of LNB; the first entry with
#                 an slof greater than the actual transponder
#                 frequency will be used

Example:

S19.2E  11700 V  9750  t v W15 [E0 10 38 F0] W15 A W15 t
S19.2E  99999 V 10600  t v W15 [E0 10 38 F1] W15 A W15 T

Everything below (and including) 11700 will be considered "low band"
and will use the first DiSEqC line. Everything above 11700 will be
"high band" and use the second line. There could even be more than
two lines, dividing the frequency range into more sections.

In the original data above, the 00000 will cause _all_ transponders
to use that line, and the 99999 line will never be used. Don't know
why he did that.
