I have now a viaccess cam with a TNT card fitted to my duo 4k SE, and I hope installed correctly though the smart card message is that I 'do not have the rights to the program'. I cannot find a procedure to instal TNT channels into the system. I have had a go, but nothing decrypted yet. TNTSAT has been selected as an operator, so partially there, though the 'rights' message is still apparent for F3 channel. TNT card works well in a French TNT receiver. Does BlackHole have to be installed ? Just a bit confused and overawed here.
