just a general question guys. been with virgin media for about 7 years now have the broadband and all channels think the missis is paying aprox 42 per month ( no phone ). we have a 55" plasma which we have had couple of years, the sd pictures ok on virgin as we got used to picture but all this hd just wanted to know is it really worth changing to sky hd? for better channels picture etc. and would it work out cheaper than virgin?
