Gt v8 uhd is cheap plastic shit box but for me is important the server Mars.This server is excellent,stable without any trouble.Sky De,Uk, It works fully ,no uhd channels,Nova Greece,Total tv,Movistar,Canalsat no uhd channels and many other providers .You can put your own c lines too, no problem.
Someone wrote here and on another forum that if you use your own lines they would be shared. I don't know if it's true.
