Matrix and Nagra

[NegativeIQ]

Hi,
I consider buying a Matrix Reborn so I can get my local provider directly on my PC. It uses Nagravision 1. I heard that's no problem for matrix reborn.
Here's the problem - The smart card given to me by the provider is 'married' to the receiver and will not function in any other receiver (not even an identical one). I do have a number called "CA Number" though.
I don't want to make any changes to the card because I don't want to risk looping it. I heard there is a way for matrix reborn to emulate the correct receiver id.
Can please anyone explain how do you do that?
