Now in the manual for the TV is says all 3 hi-def inputs accept the 720p format. But I've read that the TV actually degrades 720p to 480p!! Why on earth would it do that!!??? Would a 720p picture downgraded to a 480p look better than a standard 480p picture? I've always thought that if a TV didn't accept 720p that it would upgrade it to 1080i. Now why on Earth wouldn't this new Sony either: a)accept and play a 720p video /// or b)upconvert it to 1080i??? Why the downgrade in picture quality? I want to play all my 720p Xbox games in all thier glory, not stinking 480p after doing some reading, i've read people state that the sony 500 series downgraded the 720p to 480p and that the 510's upgrade the 720p to 1080i?? So which is it???
