This has been already discussed on the ML, look at the archives.

I remember that the driver developpers wrote that it is not possible to send
a scrambled stream to a DVB-S and get back a descrambled stream.

But you can put the CA-Module in a PCMCIA slot of your PC or your laptop.
You need to write a driver (look at the DVB-CI standard EN50221, freely
available at www.etsi.org ).
You'll be able to descramble only one stream at a time, but if you have
NOVAs you can record scrambled streams with the associated ECM stream, and
descramble them later.
