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?

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?

Not sure. How can I check that? /Erik
