I have done more experimentation and have some curious results:

I installed Zapping from freshrpms. Sudenly my TV card works fine. I can 
change channels and I can view the feed from the video machine's output. 
Only problem is, whenever I click on 'preferences', the program crashes. I 
restart and everything runs fine again. Just can't change any preferences in 
the gui window. Would have to edit the config file by hand.

However, tvtime still displays absolutely nothing. I have checked that all 
my settings are ok (broadcast tv). Just nothing. No sound, no video. And 
nothing when I play the video machine.

Kmplayer and kplayer still don't display anything at all. Kmplayer tells me 
that there is no device.

Any ideas?
