Hi Johannes and Michael,
as it was raining, my weekend was boring, too :-).
So I dug into the driver why xawtv didn't work for me (while it had 
worked at some time).

What I found out is, that xawtv queries the device for its capabilities, 
but (at least for my card) the driver claimed to not to have a tuner, so 
xawtv didn't tune.

The patch below works around this (however I am not sure that it is the 
right place)

I have an FSC rev 1.3.

lspci gives:
00:09.0 Class 0480: 1131:7146 (rev 01)


The only problem I still have is, that the tuning seems to be a little 
bit off for some TV stations as the sound is very sluggish for them.
