Hello everyone, help needed.

I have a NOKIA sat receiver 9761C mediamaster.
Inside is a smart card on which was written nagravision.
Receiver is used for cablecom (Switzerland) cable TV. (www.cablecom.ch)

Question: what I need to buy so I can "watch" this television.
Available is also input (on receiver) for CAM modules.

When I open the list of chanels, I can recognize some chanels from ASTRA and HOTBIRD.

Is it maybe better to buy dream DM600C?
But where can I find needed files and software.

Please reply.
