I can’t seem to seen any pixelation. I (re)downloaded the movies a couple of weeks ago and handbraked them to a smaller filesize.
Maybe take a look at 2:40 minute timestamp and let me know. Right when Boromir kneels and the orcs pass by him. There a pretty jarring pixelation. I downloaded the movies twice. Had the issue both times. I cannot understand if its my problems or the file itself is corrupted.
