From what I've been reading at the HTF and elsewhere, the new Blu Ray still has some IMAX shots creep into the theatrical cut. The Work In Progress version has been reduced to one of those PIP tracks.
The included DVD apparently doesn't suffer these goofs, but there is still debate going on about the colors being different.
I've rediscovered my VHS of the 1992 Academy Awards telecast, and it's got the live musical performances done by Angela Lansbury, (singing BATB along with Peabo Bryson and Celine Dion) as well as Jerry Orbach perfoming "Be Our Guest".
Belle and Beast also appeared on stage to announce the winning animated short. (Via new animation.)
