Well, "wrong" is subjective. You'll find on this forum that one eyebrow hair or speck of dirt out of place draws howls of rage.

That I know of, the video has extra frames, causing a slight (and frankly totally unnoticeable) sync problem with the audio. The most noticeable thing is rampant typos in the credits (they were a reconstruction). Everything else is much, much less significant than those two things, IMO. Others will add that there's a missing bead of sweat on Luke's forearm or somesuch, I'm sure.

EDIT: Yes, of course we have subtitles for ROTJ. We're not complete savages here.
