A quick ‘site search’ and this came up this helpful post (among many others)…
As for ESB 1997, Adywan released a nice version in both MKV (14 GB) and AVCHD (8 GB) formats. Both are available on Usenet by searching for “adywan 1997” in the NZBKing search engine. If you haven’t used Usenet before, I would recommend NZBGet software along with a free account from the “free-usenet” provider. It might take you a day or two to download, but hey - it’s free!
^ from the Star Wars OT & 1997 Special Edition - Various Projects Info thread, by dark_jedi - the 1st thread listed up on the ‘1997 Special Edition project list’ in the Index for ‘Original Trilogy Preservations’ section.
Bluto also has a most helpful thread here - Guide to Downloading Projects from Usenet - which may be of some use too. 👍
It is also up on MySpleen, and I think I have seen it around some public torrent sites too (I’ve no idea if people are still seeding it).
A quick online search says adywan’s 1997 SE of Empire Strikes Back - in HD project thread for this (among others) is in here…
THE STAR WARS SAGA - 1080P AVCHD DVD-9 for PS3 & Blu-Ray players - Episodes 1, 4 & 5 available now
It is worth noting that the talented I’mBateman has completed and released two quality 1997 HD projects for ESB and ROTJ…
There are also other 1997 SE projects listed up in the An Index Of Projects & Help Thread for Star Wars Preservations… too - it may also be worth checking the ‘Saga’ project threads for any similar 1997 SE releases as well.
