I have his v1 with the subs intact, the darkcassidy one.
Still interested in your attempt though and the results.
up until the definitive collection boxset the return of the jedi jsc release was the only CAV version. Star Wars and Empire Strikes Back both got CAV versions in pan and scan in analog sound only. in the us, not only that but the first issue rotj was time compressed or some such and the only release that was not was the ced 2 disc caddy version.
I know it sounds a bit pathetic but i wish Jedi got a CAV full frame version as well, to finish the set.
Also the pre thx return of the jedi letterbox was not centered into frame correctly the 1993 dc and the 1995 faces were the first time this was corrected.
