[mythtv-users] Trouble with DVB-C card, only partially recognized

[Jurgen Kramer]

Hi,

Today I added an additional Mystique CaBiX-C2 (KNC-ONE clone) PCI DVB-C
card to my MythTV setup. The card is only partially recognized by
MythTV, in mythtv-setup it shows an
additional /dev/dvb/adapterX/frontendX but without the
accompanying /dev/videoX. Checking kernel messages reveals it does not
register the /dev/video component. 

Any ideas what could be the problem? Broken card? (I really hope not) 
I already put the card in another machine, unfortunately with the same
result, no /dev/video.

Here the kernel output from the 'defective' card:

The new card somehow misses the "saa7146_vv: saa7146 (0): registered
device video0 [v4l2]" bit as seen with the working card:
