I received this disc and Return Of The Ewok last week.
The editing job in the Classic Edition is amazing. Of course, knowing where the special edition shots should be, you can pick some color differences but you must be searching for them. Both sources blend together very very well.
The commentary track seems to be great (and an incredible amount of work!), although I hadn't time to go through it.
I didn't check the isolated score since I already have the Editdroid version. Hey, Garret, did you reassemble the score by yourself or did you just take any of the existing versions? Just curious.
The only thing about this edition is, as somebody mentioned, the artifacts. Editing an MPEG2 and also make it fit on a DVD5 creates a lot of them. It's a pity but, as Garret says, it is what it is.
About Return Of The Ewok, the restoration work is fine, knowing the source material (we are talking about most parts of the short film taken from a camcorder screener). It was hard to me to follow the dialog. The sound wasn't that great and... well... I'm not english, so... both things together made it difficult to follow. An interesting film, though.
I haven't seen all of the extras yet. I went for the Star Tours video. I wish it had more quality. I have a camcorder screener of it that looks better (I don't know if somebody has it), but has the problems of being recorded from the seat of a flying simulator.
I checked out the Jabba scene, since it was improved with some footage I provided. It looks better than the previous version, of course.
I also got "Indulgence", a film starring Garret itself. It has some boring parts, but is pretty funny. Garret's performance is hysterical and hilarious. He emphasizes the words a lot when he's speaking, so it's quite easy for me to follow his dialogue. The story is simple and there are some good gags ("We have a very low budget"
). Both female characters are so sweet and funny (there's a green haired nurse and a pornstar called Sprinkles). There are two "south park-ed" beer bottles, too. 
Well, I think that's all.
Nice discs, Garret.
