> Simple answer, MythTV has nothing to do with it - basically, if the Linux video drivers provide the standard interface and an unencrypted video stream then Myth will record it. So it's down to the drivers to handle that. Myth just tells the tuner to tune a particular transport and expects to get a data stream back.

Right, meaning MythTV will only work with hardware-based CI/CAM--where 
the output is unencrypted video.  It will not work with any kind of card 
reader. See http://www.mythtv.org/wiki/User_Manual:DVB#CI for a 
very-brief mention of how it must work.  (Another brief mention at 
http://www.mythtv.org/wiki/User_Manual:Setting_up_DVB-S_for_satellite#What_about_PayTV_and_encrypted_channels.3F 
).

As Simon mentioned, the hardware and drivers must do all the work before 
MythTV gets anything.  So, the best resource is:
