Well, personally, I can't say that I have "researched" every DVD or video I have ever bought. If I see something I like in a shop and it is a movie I want, I might just pick it up off the shelf, read the blurb on the back, and buy it. Star Wars is different for me, but many people may just see it and think"Hey, Star Wars is out on DVD, I might just get it..." Or they may buy it as a gift...
