Have purchased a new Samsung LCD TV. Am happy with the quality with dvds, but when watching sky, the picture is pixelated. The tv has a built in freeview which is very clear compared to the sky. If i was to change from Sky to NTL, would there be a difference in quality? I have an amstrad box which is around 3-4years old and only has a scart connection. The scart cable i am using is decent quality and was recommended by many people off the forum. Any help would be much appreciated.
