I sent a question to technical support at KNCOne.de, and they confirm the bad news that Manu Abraham gave me : the CAM/CI on the TV-Station DVB-S can
only be fed data from the tuner, not from a file.

Pondering my options, I see two of them :

(1) obtain a PCMCIA slot, and stuff my CAM in there. This may be the easiest route to take, as the CAM will still be there to do most of the work. I
would be loosing a PCI slot however, and the capability of using two tuners (anyone know of a PCI-Express based adapter card ?)

(2) get a smartcard programmer, connected serially or through USB, and port "poor man's cam". It looks like I wouldn't be able to use the CAM in this
scenario, and it would need to be emulated (which, as I understand it, is the bulk of "poor man's cam" coding).

are there more - easier - options ?
has either one of these been tried ?
anybody interested in starting a project for this ?

my ultimate goal is having a MythTV box handling multiple recordings, descrambling them afterwards
loosing live-TV would not be too big a problem, as I prefer to watch recorded stuff and skip the ads
