This particular "fix" is for chromatic aberration fringing -- see post on the previous page describing the particulars: http://originaltrilogy.com/forum/topic.cfm/THX-1138-preservations-Italian-Cut-available-see-1st-post/post/624565/#TopicPost624565. I wouldn't expect such a problem to be on a professional release.

Unfortunately, it is on the two BDs I described earlier. I believe I've heard it referred to as Technicolor Dye Registration errors. A color sometimes peaks out far beyond where it should be. Universal just used old masters for both and didn't bother fixing. As I am very fond of both movies, Rope more than the 1943 Phantom of the Opera, I'd love to see if there's a way to make a corrected version.

Anyway, thanks for the informative post. I didn't know EE could be reduced as well, that's great.
