I think ADM has done a DVD of Aladdin restoring the 2 sound changes. However, the main problem with the Disney releases is that the LD sets are expensive and hard to come by (on ebay at least). I actually asked if anybody would want to help out with a Lion King set that ported the Making Of special from LD to DVD. Nothing ever came of that however (as the auction I was watching finished).

I think Aladdin is one of the cases where it's not so much things were "changed", but things were reanimated. It would be nice to have transfers from all the LDs that contain unaltered versions - but that falls into a dangerous area. Plus, you generally don't want to mess with The Mouse by distributing a bootleg DVD. Still, I'd love for some sort of discussion to occur here in regards to the Disney LD's and possible preservation attempts: "The Making of The Lion King" being at the top of my wishlist.
