Sorry to keep chatting in this thread that was changed from "New" to "Invalid".
I still believe it is TVH doing something strange during the startup sequence that causes these "adapter 2 frontend 0 frequency 0 out of range (950000..2150000)" messages from kernel in the syslog:

I downloaded dvb-apps. I shutdown TVH and did a SCAN according to the info at
http://www.linuxtv.org/wiki/index.php/Scan to create a complete channel list for the satellite THOR 1.0W (actually it is 0.8W).
After that I tuned each adapter to a channel using Szap-S2 app (http://www.linuxtv.org/wiki/index.php/Szap-s2and). Then I started TVH again and voilaaaa! No more messages in the syslog about "frequency 0 out of range"! :-)
So it definately looks like that when TVH starts it initiates the adapters without having a valid frequency set?
