Correct. the adapter1 is for DVB-T recaption, and aslo the scan was for terestrial Attika Greece, provider for Greek Digital tv is Digea. i never spoke for dvb-s reception, please have a look in chanenls.conf file from my first email.

Did you receive the email with db results and kaffeine gui picture from one channel?

This confused me.  The frequencies quoted earlier looked DVB-T-ish, and
Digea is (as the name hints) terrestrial (but that's Latin) :-)
