The little interviews at the beginning definitely need to be preserved, those alone make this worth it.
Speaking of which, I remember renting a set of the movies after the theatrical release of the Special Edition, but before the home release. I think they were a rental only edition of the special editions (the kind that studios used to release so they could make extra money off the rental places before they made the sell-through release), but I guess they could have also been a really late set of the OOT.
The reason it would have to be really late is it had a short featurette about the restoration for the Special Edition on it, but it was a different one from the one on the sell through VHS set. Does anyone know anything about this?
