Of course, as we now know, there were different "original versions", as explained by Ben Burtt in the commentary track of the "A New Hope" DVD. There is, of course, the one with the original mono soundtrack, then there was a 2-channel Dolby track, and a 6-channel Dolby track (for the 70MM prints). Each one has varying differences in dialogue and sound effects. The recreated DVD could have possibly been recreated to resemble one of the stereo prints, since the version I originally saw in my local Century Complex in Sacramento, CA in 1977 (or was it '78?) was a 35MM 2-channel Dolby print with the redubbed Aunt Beru voice, the different Death Star voice (i.e. "30 seconds and closing'), and minus 3PO's explanation of the tractor beam.
I also did see the original mono version, in a 35MM cropped 1.85:1 print at the Starlite Drive-in (also in Sacramento, and since been demolished). This had the original Aunt Beru voice, the original Death Star voice, and 3PO's explanation of the tractor beam. This print also had a trailer for "The Empire Strikes Back" at the end of the credits (the one with Harrison Ford's narration). The "Story Of Star Wars" album was also based on the mono version.
I would like to see the mono version in some form. E-mail me if you could.
