I use scan from dvb-apps, the command is
"scan -o vdr /root/dvb/Astra-19.2E > /etc/vdr/channels.conf"
where /root/dvb/Astra-19.2E is file with "S 11567500 V 22000000 5/6"

I use cx88-dvb driver but many modules are loaded with it see
http://kedge.wz.cz/dvb/lsmod.txt

Scan console output is in file http://kedge.wz.cz/dvb/channels.conf
and the result in http://kedge.wz.cz/dvb/channels.conf

When console shows
__tune_to_transponder:1508: ERROR: Setting frontend parameters failed: 22 Invalid argument

the dmesg prints
DVB: adapter 0 frontend 0 frequency 8175750 out of range (950000..2150000)
