Oh! It was definitely too late on monday night. I tried again and could watch and listen to many more channels. (FYI: Before I continued with the changes below, I restored the original values 0x44 / 0x4c in lnbp21_set_voltage(). This time I checked twice ;-) > Anyway, let's try whether 22kHz and DiSEqC are generated by the stv0299 > in the tuner.

Yes. Many channels working (e. g. channel #1 - #48, using latest version of dvb-apps/util/szap/channels-conf/dvb-s/Astra-19.2E in CVS), some get a lock but no video/audio output (~ #50 - #76, maybe scrambled?), still many channels without a lock (> #80). Now I can use the scan utility, output: http://www.bernd-stark.de/dvb/scan.out.gz . (scan -v dvb-s/Astra-19.2E > scan.out 2>&1) Cool, I think we're getting very close now!
