I have a 3.2 metre dish (the big one anyway) and that gives us perfect pictures on all channels. Mrs sqad has a separate digibox in her room as we watch and are interested in different channels.
Both boxes HD. Bit expensive, but what the hell have you been working for all your life ;-)
Great Drama very sad story but told with emotion and atmosphere of the era, good that it was just two episodes and not drawn out over weeks as we were able to keep up with it!
