shame all these sites doesn't really use png (or another lossless format)
what is the point of having the pix that are lossy? cause what you are comparing are crappy low quality jpgs not really what the releases really look like.
*shrug*
i guess it is useful for seeing typesetting 'et al, but not video quality.
