The Pre ANH disc is just an exact recreation of the VHS bootleg.
If I were to alter a scene like that , it would actually be for my own edit of EP IV, which will be done after I have the dvds and know more concrete on EP III.
BTW, I guess someone on these boards has a reel to reel version of that scene in question.
If it manages to get transferred to a more useable format and passed my way, it'd be appreciated.
