Hi, this seems to be a huge problem with sky looking bad, ive posted and read threads on this subject, people i work with who own it have the same problem and each time its identical (picture was fine on my old tv etc)
The answer is simple and makes sense-
Consumers are interested in quantity rather than quality (100's of babestation channels anyone!

) and will pack as much in as they can at a big cost to quality.
Picture is generally better on a new tv, any flaws in the broadcast will be nice and clear for you to see. Try channel 4 (good picture) and then switch to a nice low budget channel like Majestic tv etc and you'll see a big difference. Its not the tv's fault. As ive stated, i set the picture up using the DVE DVD and on a good broadcast channel the picture is stunning, heres my settings but after seeing this done before and a huge difference in settings i think its down to the individual tv. This was calibrated after 1 week of ownership (new tube etc)
contrast = 72
