Here's off the top of my head (no disc order):
-Concept art
-Many, many trailers
-Classic Creatures: Return of the Jedi
-From Star Wars to Jedi
I'm sure there's more, and I'll check later (and by that I mean after school). Note that with Creatures and SWTJ that there are burned-in subtitles of some language; Japanese or Chinese, I can't tell.
