Chainsaw Ash mentioned the esb theatrical 35mm audio i believe this is on the 1985-86? CAV release which was analog only.
I have the laserdisc which does not have laser rot though my companion piece to it star wars does.
I think this is also a dark jedi preservation from years back on dvd-r, except the audio was what downsampled to dolby digital 2.0 at i cannot remember what setting.
The CAV transfers were two of my faves. Only limited by the fact that they were full frame.
Star Wars was a solid transfer and the color was pretty good and the picture sharper than the clv widescreen release.
I always wondered why the letterbox releases where so soft and grainy compared to the full frame presentations.
Another thing i wondered was the THX faces tapes in full frame on VHS never released on laserdisc a different transfer than the definitive collection or just cropped and zoomed in.
This was available on hong kong laserdisc with burned in subtitles and full screen. I stilll suspect it to be a bootleg dubbed from the VHS tapes.
