If you want to be really anal about it you could perhaps restore the original preface to Empire and Jedi using the broadcasted '97 special editions. Empire used the same preface as Star Wars so I understand why you used GOUT-SW as it was from a better source, but maybe the broadcasted '97 versions yields even better results for a possible future version, at least for Jedi. Just a thought I had. Just avoid ANH as it was redone in '97 for some reason. I guess the Lucasfilm - logos will be harder to find in better resolution though, the only way I can think of is a very well made capture of a Pan & Scan LD or a scan of an actual print. ;) I don't know, maybe the GOUT-upscale you used looking good enough or better than using the '97 sources.
