Sorry to disappoint you guys, but those screen shots are of the Rowman bonus disc set. If you're lucky, some copies may have an .nfo file included helping to identify the discs.

There's is also a 4th Rowman disc 'Definitive Laserdiscs Extras - The RowMan Transfer' with all the extras from the Definitive Collection Laserdisc set.

Russ's galactictradefederation.co.uk site is invaluable for info & screengrabs of this sort of thing:

There's also a bit of background to both sets in this thread:

From what I remember, the "The Ultimate Supplemental Collection" by RowMan was designed to look like the Editdroid releases. This was in the days before we knew of the existance of the Editdroid Four Disc Special Features Set.
