I had heard these sources were cropped. Either way they look great especially Star Wars. This may be the best quality version of the films with the proper coloring that you could get. As for the special edition trailers.
I think the 1997 trailer on the 2004 bonus disc actually used an OOT shot where Wedge helps Luke out and shoots a TIE right before the X-wing would have crashed into it. There is a very big noticeable scratch at this point. But then watching Dark Jedi's I swore I saw the shot as it appears in the special edition. So if there are two versions of that trailer maybe I wasn't imagining things. Either way Dark Jedi's '97 extras disc is pretty good and I'd be willing to trade it for some other stuff. I'd reccomend wathing that first before trying to transfer any of the '97 stuff just to see if it would have a good chance of being an improvement. The one thing the '97 vhs tapes have is a small bumper at the end with the 3-d logo and the voiceover "Now see (name of movie) the way it was meant to be all along."
My wishlist would be for someone to capture the 1995 interviews and "One Last Time" trailer since the existing Rowman discs of those are vhs sourced and not from the Faces laserdiscs. Watching the dvd transfers again they looked like the black level was too high as well. I don't think it would be too hard to improve those. Now I wish I had bought the used '95 set I saw in an FYE last summer. But I'm having problems with my DV capture box anyways:
