It seems to me that many of the issues we are noticing with 2.1 (eg. frame freezing while R2 talks on the BR; jerky orbital shot of Tatooine; inconsistent opening crawl speed) are, in fact, issues that the original theatrical release may have had; and the fact that the picture quality of this remaster is so good, itmakes such imperfections wih the source that much easier to spot.
In other words, it's Lucas' fault, not Harmy's.
@Harmy, what is on your list of fixes for 2.5 thus far?
