the theatrical mix was analogue to begin with star wars had no digital mix til 1985 and back then they had no digital playback equipment or very little. they had released return of the jedi under the thx program in 1983 with digital sound but how many theaters got that probably 5 if even.

unless you have access to the lucas master tapes in his private little skywalker ranch vaults the best you will ever get of the stereo mix is the analogue laserdisc. by the way this was only on the cav release. the clv did not run a proper speed or was sped up to fit the running time and laserdisc.

the clv and cav releases that have the stereo mix all suffer from laser rot problems so a pristine copy is hard to come by.

quote" I didn't know that the '77 Dolby Stereo mix ever made it to VHS. Interesting."

i did only once as on the rental only 20th century fox release which thestarkiller preserved on dvd.

the re-releases all were the later 1985 digital remix.

not sure but i think the non rental from 1984 may also have the theatrical mix.

so without any further proof i think the 84 release is the one you want and not the 1985.
