Hello, Hermann,

thanks a lot for your hints !
I am so embarrassed, but indeed everything worked fine -- the only 
problem was, that I took the antenna of my standalone-dvb-t-box and put 
it on the Terratec-card - not considering that it is an active antenna 
which needs a 5-V-supply over the antenna cable. Obviously the Terratec 
card doesn't have a 5-V-output on its antenna input, so this active 
device didn't work. I then took a very old indoor aerial (at least 25 
years old model) -- and soon the scan with Kaffeine was able to fix 22 
channels .... ;-))
The automatic load of the cx88-dvb module can be achieved via the 
/etc/modules - file in Ubuntu. I simply added the name of the module in 
a line in this file -- and now everything works.

So, now : PROBLEM SOLVED -- Thanks a lot to everyone who was contributing !!

Regards,

Martin
