According to https://originaltrilogy.com/topic/Harmys-STAR-WARS-Despecialized-Edition-HD-V2-7-MKV-Released/id/12713, one of the sources used in the Despecialized Edition was a Reivax DTV capture of the 1997 Special Edition. It was also used as a source for the Respecialized Edition. I would like to acquire a copy but I can’t find it anywhere. Any help would be useful. Thank you.
Mod Edit: just for info… there is some discussion on the Reivax DTV version of the 1997 SE (amongst other projects), here:-
