No, the CI handling is present in the firmware. (Other parts were missing.)
Donīt use the Windows firmware since it is missing bugfixes and other features 
(like NTSC support, pan/scan mode selection ...) which I added to the 
firmware and which the driver relies on.

Thatīs right. For crypted channels just set the PNR and the
DVB_CHANNEL_CA flag and forget about the normal video/audio PIDs.
(Of course you also need a CI-CAM and a valid subscription card)
