Alex,

Thanks a lot for your patience. I am slowly starting to understand the 
whole thing.

  ./scan-s2 -5 -o zap -x 0 -s 0   dvb-s/Ku-band/S19.2E.ini > channels.conf

Works fine, finds many fta channels.

  ./scan-s2 -5 -o zap -x 0 -s 1   dvb-s/Ku-band/S23.5E.ini >> channels.conf

Even the second LNB works now, finds some ftas :)

Results of the scan give very often zero APID, VPID:

Sky Cust Ch:11934:v:0:27500:0:0:4505:5
Cartoon Network Game 4:12012:v:0:27500:0:2603:8005:5
Video Application Val:12012:v:0:27500:2518:2519:8015:5
Sky Bingo:12012:v:0:27500:0:0:8032:5
Sky Bet, Vegas & Sky Poker:12012:v:0:27500:0:0:8076:5

Please see the attached screenshot for results of the scanner under 
windows - APID/VPID are almost never zero. Do the missing values have 
any negative effects?

If I want to use e.g. kaffeine, should I just rename and install the new 
szap-s2/sca-s2 binaries systemwide?

Thanks a lot for your great help.

Pavel.
