Interesting! I (mistakenly) thought that the '93 TESB and ROTJ mixes had some different content.

That might not be a mistake. I have always shied away from the 93 mixes because of the changes in Star Wars, so I don't know them as well (even though I'm the first to admit they actually sound very good).

Certainly if all of the 93 mixes are all based on the 70mm multitrack mixes, there'd be room for the differences on the 70mm Empire mix to make their way onto the 93 mix. I just don't know of any.
