I saw an article late last year(Popular Mchanics?) on the pixel amounts of SD/HD and film. Film has billions of pixels per frame and it is cut back to size for it to fit our meager big screens in the house. Kind of like when I back up a DVD from a dual layer DVD and shrink it to a single layer, when that back up is played on a larger screen than my own 36" crt it looks a little fuzzy as some of the content was removed to shrink it.
