I have recently bought a second KNC1 TVstation DVB-C+ card for my MythTV 
server but tuning with the new card doesn't work at all. The two cards looks 
identical and identifies themselves in dmesg identical (apart for some memory 
adress differences). However, upon closer examination the only thing 
different was the text on the SAA7146 chip. The old one read:
SAA7146AH
CG1902
TtG06404

and the new:
SAA7146AH
CG1902
TtG06424

Both cards has a Cineview CI connected.
Runing dvbscan gives this:
