Blu-ray aspect ratio
According to the Blu-ray packaging for both How the Grinch Stole Christmas! and A Charlie Brown Christmas they are in 16×9 1080P.
My question, is how do they get 16×9 HD from 4×3 originals ?
Are they 1) cropping the top and bottom off the originals, 2) stretching the originals, or 3) is the packaging just wrong ?
