Interesting. I have Technisat Technicrypt CXV (Conax) inserted and none of
the channels is decrypted. Tried czap, vlc, vdr.

czap - no errors reported but no useful data output

vlc - reports detected CAM doesn't matter if it's really inserted or not:
[00000338] dvb access debug: Opening device /dev/dvb/adapter0/ca0

[00000338] dvb access debug: CAMInit: 16 available descramblers (keys)

vdr - says only

byte of video stream
I know that vdr should report something about detected CAM but nothing in
it's log file...
