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?
