Can it be confirmed if there are 1985 remixes for ESB and ROTJ? I just watched the SWEs for both, and both sound like other 1980's Dolby Stereo releases.

ESB is confined mostly to the front with occasional sporadic surround usage. The dialogue alternates between muffled and strident, with the track overall feeling slightly limited. (I had to raise the volume significantly to match regular levels)

ROTJ is far better with better surround usage, better presentation, fuller sound, and better mixed dialogue.

Oddly, neither has any real sound panning as do both Raiders and Temple of Doom. Maybe then these are remixes and the original tracks have panning intact?
