I have the Limited Edition set and the only extra stuff on it is some stuff in Jedi. None of the deleted scenes or alternate openings/closings or that very nice "making-of" special that were featured on an earlier pressing. Here's a rundown of what on the Collector's Limited Edition set that isn't the shows themselves:
