One feature I am eagerly waiting for is being able to create a Blu Ray script (which you can't do now, even if the discs are in a player), but once the vault comes out, that would certainly be a great feature...however, you CAN currently create favorite scenes for BD's that you have imported, but only playable once the disc is in a drive, obviously. I have created several Avatar favorite scenes, great for showing off how great the picture is!
