You might also want to try using transponderlists from joshyfun: 
http://joshyfun.peque.org/transponders/kaffeine.html. Network scanning 
does not give all channels in some cases.

On the Hotbird, I've got 1921 services, including encrypted radio and TV 
channels, but without data services. This is on a (well supported) 
Technotrend S-1500, so these should be all channels.
