Yeah, there's plenty of Disney LDs crying out to be preserved properly. Beauty and the Beast CAV, Aladdin CAV, the REAL Academy ratio version of Lady and the Tramp, various deluxe CAV sets of the classic films (with some extras that still haven't shown up on DVD or Blu-ray), perhaps even an X9 capture of Song of the South.
Molly has been working on a Disney LD preservation project but it hasn't seem to have gotten very far as of late...
