Hello
You need to extract so called "boxkey" from STB. But i'm not sure if it's legal. Read some sat boards. It's the same technology as in dvb-s.

I use my TV with CAM module. I think you could ask to your service provider if it will work with CAM module. I think it will.

And please search on consumer rights on your country.
You have a right to use/watch TV with CAM modules since your TV has a digital tuner already, you don't needed to pay for STB...

Also you can order a CAM module from internet for try and if it's not working, you can send it back and request money back.
Here in Turkey, we could return goods to seller under one week.

I don't know how could you extract and use that key from your card. I think it will be outlaw. Instead, read the consumer law of your country and request your rights.
Real hacker don't get outlaw, but use laws for itself
