hi everyone, I want to build a cardsharing system for 7-8 receivers.

I just want to know what kind of hardware/software I need ?

how to setup this system ?

I and my relatives have 7-8 receivers, we try before some cardsharing but all of them is terrible, always freezing, we can`t watch anything. So I decide setup own cardsharing system, I have just browsed internet, all tutorials mention that how to set ip address for receive encryption but couldn`t find how to build a new cardsharing system ? I will buy original receiver or original card and then decrypt and share with my relatives.

Should I buy Dreambox or other linux box works ?
If original package`s card doesn`t work other box what should I do ? I mean do I decrypt and send codes with original box ?

I want to know these for Digiturk (Turkish football league broadcasting) and I can not ask in Turkey, it is not allowed.

I thanks in advance for everyone answered or give me any link about it.
