Hi I have a Pace digital (itv) box. I can receive all the currently available channels, picture quality varies from being amazing (say star wars the other night on 3 and a robocop on 5 the other day) to merely average with blocking appearing on the screen during transtions from dark to light scenes....My question... Do they crank up the signal at certain times? cos if the government wants people to change to digital they need to keep the picture quality at the standard I see when they show films. BBc seems worse than ITV. Anyone else notice this?
