Hello,

I recently bought new KNC One TV Station card with Cineview CI module. When
I installed it, it was detected and worked with no problems. I just noticed
that tuner is not that sensitive and has a little problems with signal
strentgh in some cases (rain, bad weather) where TT 2300S Premium didn't
have. The problem got bigger when I tried Cineview module. I inserted
Viaccess CAM module and RTV Slovenija smartcard. When I inserted CAM, card
at the same moment lost lock of signal and signal was not good enough to
lock again. When I get CAM out of the CI signal doesn't lock until I restart
szap.

I think that this card is not supported directly because lspci reports
Unknown KNC One card. Is someone working on drivers to support this card?

lspci output:

dmesg when CAM inserted:

I would realy like to know if card will be fully supported. I can help
debuging problems and test solutions whithout a problem.

Thanks!

Regards,
Gregor
