Thanks for your reply. I did a little Googling (I had no idea there were so many fan edits and bootleg transfers out there) and found this page on the Dr. Gonzo edition you mentioned:

Reading up on that page I noticed these remarks
The commentary on A New Hope and Return of the Jedi included Ralph McQuarrie, Dennis Muren, and Ken Ralston, while the Empire Strikes Back commentary added George Lucas and Frank Oz to that list. Second, the discs boast a remarkable number of chapters: A New Hope sports no fewer than 79 chapters, each of which has a thumbnail link from the eight pages of chapter stops. The production notes are rather interesting, and even make reference to the 1993 Definitive Edition LaserDiscs that were used as the source material.
That certainly sounds like mine, chapter wise. There are a BUNCH of chapters (79 total I believe), though navigation isn't the easiest. I will check to see if there is actually a commentary option in the menu. Strange that Dennis Muren's name would pop up on the screen though, as if he were making commentary, when in actuality his voice is absent.
