Also, are there around other Classic Creatures preservations? EditDroid is taken from the same RowMan's material (VHS)? Or from a laserdisc? And, if from LD, is the last version used (the one with the digital soundtrack) or the old one?

All of EditDroids documentaries came from laserdisc. I don't know about digital vs. analog audio though. But given the very limited mono source material, I don't see how that would matter much. Some of them, I forget which, had the burned-in Japanese subs. They did replace all of the trilogy movie footage and some of the clips from other movies with cleaner sources though.
