In the case of first generation encryption, the codes were changed twice a week but it was still hacked. We have to thank hackers for sticking with it and allowing us to follow our hobby. As for second generation, it may never be hacked but the key searchers will carry on....it's in their blood.doggy said:i read in an artical by the irdeto md that they change codes every year regardless if its been hacked. so whats the point in trying to hack it?
