duo 4k se

Hi, I'm new owner of VU+ DUO 4K SE BT Edition with 1x slot DVB-C tuner. I also own Technisat Technistar K4 ISIO PVR device. It has some annoying bugs, but in general it is a very usable device, I like it. I switched to VU+ DUO 4K SE in hope, that I will get more features and will be more...

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...
