[linux-dvb] DVB-S Channel searching problem

Hi,

I have a problem with DVB-S channel searching, the scan command doesn't find all channels in Linux on Astra 19.2E.
It works in Windows.

For instance the scan doesn't find RTL2, but if I add to channels.conf
RTL2:12187:h:0:27500:166:128:12020
then szap -r works correctly.

I have TeVii S460 DVB-S/S2.
Linux kernel 2.6.28.

Can anybody help me to find out why the scan doesn't work correctly.
I've compiled kernel from source so I can apply patches or change its settings.

Regards,
Roman
