Okay, I'm a pirate, but I'm no bootlegger. Whatever edits I have I make copies of freely. I may charge a buck for the case, whic is more expensive then the DVDs but that's it. Of course these guys selling Fan edits and fan films at cons are not in the right either. At most they should sell for maybe $5 but they are charging $20-30 a pop for what the good people hear have worked hard on. And they are making money off of other people's hard work. When I used to staff cons, we had zero tolerance for bootlegs so we would just shut down their booth and kick them out of the con. This is pretty harsh.
And here's the thing, Lucas doesn't have to be part of the MPAA, they can do it to anybody selling movies of US movies I think. Hong Kong and Asian films they can't really touch unless an American studio has distribution rights like Columbia with some of Jackie Chan's movies. Even then, I think if it's a legitimate product, the sellers may get away with that since it's sold as a collectable import.
My details may be a little fuzzy, though.
