One minor glitch that I notice when watching SSE, is in this shot: https://picasaweb.google.com/102542760950977079734/StarWarsSpecialEditionChangesHD#5514975327942007154

There’s a point where there’s some artifact or warping in the bottom right corner.

Also, I wouldn’t normally have mentioned it since it’s not a big deal and SSE isn’t meant to be 100% dirt free, but since it’s right nearby where I’m talking about: the very next shot (after the wipe) has some pretty huge visible damage on a few frames, from what I recall.
