Hi I wonder if anybody has the same problem
I am in Glasgow and get most channels on most satellites ok
When I go to Sport1 / Sport2 /hungary and Sport1 and Sport 2 CZ
I get freezing and glitching
I have tried 3 different box's and all show the same problem
all other channels work ok
I get 68% quality on box on these channels
