Hmm. Ok. I've tried lots of different stuff now, but no change. Still unwatchable with two DVB-C cards in the machine. Tried to measure the signal strenght with the femon plugin, but I'm not really sure how to interpet that the signal-to-noise (SNR) ratio goes between ~87-91%.
If it is the signal strength, what do I do? Buy an amplifier? Use the shortest possible cable?

How have you wired the 2 cards to your one cable cable? The direct cable signal is usually not able to drive 2 receivers.
I've just taken the coax cable from the cable-tv wall outlet, plugged in the first card and then used a short coax cable and connected the two cards.
Do you have error messages in /var/log/syslog?
No, no errors at all.
- Use the new card "in place" of the old to make sure that this
new card is not DOA
Check. Doesn't seem to be anything wrong with either card.
- Place the new card (alone) into the intended slot.
Check.
- use different slots
Check.
- Use the old card as second board
Check.
- Remove all hardware not required
Nothing in the machine except the two DVB cards and an AGP graphics card.
- Tell the BIOS to reassign the PCI resourses
Tried to fiddle with the PCI settings in the BIOS, but no change.
Are those interrupt shared?
Not sure. How can I check that?
