Self-reply because I’m outside the edit window: the dvd “original” releases are based on the laserdisc, but supposedly they modify it to restore the pre-1981-re-release title, so I’m actually wrong!

I can’t find out if they fix the 3% speed-up from the laser disc. The audio mix, at any rate, will be a combination of the three (stereo, mono, 70mm) original mixes, like on the laser disc, so identical to none of them. The source should predate the replacement of Latin script with made-up letters (not conceived until ROTJ then retrofitted on some releases of SW and Empire) so that’ll be intact unless they “fixed” it.

Still stuck with sub-ordinary-dvd-quality picture, as far as official releases go, so that’s too bad. Oh well, fan 35mm scan projects solved that problem.
