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

Hello, Hermann,
I tried it -- and succeeded to load the driver, so I now find the
devices in /dev/dvb -- thanks a lot !
But:
-- how can this be done automatically during boot ?
that is also somewhat distribution dependent, but
install cx88xx /sbin/modprobe --first-time --ignore-install cx88xx && { /sbin/modprobe cx88-dvb || :; }
in /etc/modeprobe.conf should do. Run "depmod -a" after adding it.
and:
-- I then tried the "scan" of my homezone (=de-Ruhrgebiet), and NO
channel was found. (This must be an error - I am able to receive 22
channels with a standalone-dvb-t-box.)
-- kaffeine isn't able to receive any channels, too.
I append the output of scan:

So, now: Why can't this card receive any channels ?? -- or did I miss
something ??
The card is auto detected since 2.6.13, previously people even used
card=19 for it, since it is based on that design.
Only support for the analog input was forgotten, but added now.
Else it is known working, likely you need a better antenna.

I can't see anything wrong, maybe somebody else is more aware.
"scan de-Ruhrgebiet" should find everything, if the antenna is good
enough.
You also find a de-Ruhrgebiet "channels.conf" in dvb-apps from mercurial
at http://www.linuxtv.org/repo in util/szap/channels-conf/dvb-t for
"tzap".
Cheers,
Hermann
