FreaQ, I solved the mystery...
Take a look at this post: "On my discs, Making of SW and SP FX were taken from Rikter's laserdisc captures and Star Wars to Jedi & Classic Creatures were taken from my own official VHS releases."
Here you are! I don't know if there are any other "From Star Wars to Jedi" version on other project than RowMan's, but his one is from VHS... so, it is explained why (apart the obvious green line that clearly is not part of the capture) the picture size is different; the video quality and the color resolution are lower and the details are worst...
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?
Every day I discover something new (thanks to all of this forum members), and this project seems near its beginning... still, I need someone (or more than one) who would help me with the dialog transcription of the supplemental materials!
