Thanks for the reply. I have checked the cable, and to be sure the cable 
wasn't faulty, I contacted KNC1. They sent me a new cable for testing 
purposes that arrived within two days. Excellent service!

Unfortunately it didn't change the situation: the results are identical to 
what I reported earlier. 

So, zapping to channels works,

fraggle:~# czap 'Nederland 2'
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
123 Nederland 2:388000000:INVERSION_AUTO:6875000:FEC_NONE:QAM_64:181:182:8005
123 Nederland 2: f 388000000, s 6875000, i 2, fec 0, qam 3, v 0xb5, a 0xb6
status 00 | signal aeae | snr b6b6 | ber 000fffff | unc 00000047 |
status 1f | signal d2d2 | snr f3f3 | ber 00000798 | unc 00000004 | FE_HAS_LOCK
status 1f | signal d2d2 | snr f3f3 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal d2d2 | snr f3f3 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal d2d2 | snr f3f3 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

but recording / trying to get data from the device

fraggle:~# cat /dev/dvb/adapter0/dvr0 > test.mpeg

results in empty files, and the ejected/inserted loop keeps running as shown 
in my first message. I've managed to flash the Alphacrypt CAM in a PCMCIA 
slot on a laptop, so I guess this is not the showstopper. The program card 
works in an other device, so this isn't it as well. I rechecked that the 
TV-station card has its own IRQ, which is the case.

Could it be the CI module? What do you think?

Thanks,

Rutger
