The NDS CAM is only licensed to OEM.
For OEMS it is cheaper( or maybe part of the license?!) to make it part of the 
mother board and not a separate part.
So, NDS CAM is inseparable from any NDS decoding BOX.

NDS Open?! I sent them a few E-mail and got 0 replies.

The Decoder is not on the smart card, the smart card interface is too slow to 
do MPEG2 decoding, and it's CPU is getting stronger all the time, but still 
it's not capable of MPEG2 decoding in realtime.

The decoder (CAM) is part of the motherboard when you have an DNS box ( Cable 
or SAT).
You need diffrent CAM for every encryption method, a few CAM models can 
decrypt many encryption systems, but you still need a valid smart card.
No, there is no CAM for decoding NDS.   

Think of it this way the CAM is a sort of hardware PGP program and the Smart 
card have your secret key.

Good Luck!
If you do succeed, please send an E-mail to one of the Sky Network forums, 
many Sky subscribers would be glad to hear it.
The Sky subscribers base is NDS millking cow and if they never got a CAM, what 
make you think they will make one for Israel?

Why?! but you have a "PVR" "Yes MAX", I haven't seen one, but following NDS 
tradition: It's probably air tight and encrypted to the bone.
