I just purchased the Definitive Star Wars Trilogy CAV LDs at this big second hand retailer (Amoeba in SF), for about $45, but it didn't include the box that holds all 3 sets of the movies, or a hardcover book. I just went ahead and bought it but I have a few questions: - is it somewhat worthless now? - sound: is it in Dolby ProLogic? or in plain 'stereo'? Thanks!
