Could you tell me how? I've tried with S 12188000 H 27500000 3/4 and
it doesn't find anything.

Try also scan-s2 with:
S 12188000 H 27500000 3/4 AUTO QPSK

I use driver from vanilla kernel 2.6.28 which have DVB api version 5.0.

The console output should be http://kedge.wz.cz/dvb/scanconsoleout.txt.

I've tried to run scan and scan-s2 on "S 12188000 H 27500000 3/4"
were the "RTL 2 Deutschland" channel should be and neither scan found anything.

The console outputs are here:
http://kedge.wz.cz/dvb/scan.txt
http://kedge.wz.cz/dvb/scans2.txt

I don't see any problem with scan output. I don't have the same card as yours, so only guessing...

Do you have a diseqc on the way?
 

If you want me to run the whole scan for "S 11567500 V 22000000 5/6" with -vv
let me know and I'll do it.

No, no need.
