Hi, I'm looking at buying either a 42" Panasonic PV500 or a 42" Hitachi PD7200. I would just like peoples opinions on the Picture quality from a Sky box. I've seen both in shops with the standard Finding Nemo DVD and they look superb but I mainly watch Sky. My current Sky box is a 4 year old Grundig (not sure what model). Would I get better Picture Quality from newer Sky+ box? I know the picture quality will improve with HDTV and both these sets are compatible but depends on the pricing from Sky ! Thanks.
