Well, I don't think that the distribution of fan-edits and never-released-on-DVD material is really piracy. There aren't any exact copies of products that have been released on DVD, here.
Ok, all that is unauthorized, and using copyrighted material, but it's just re-edits or preservation. And I really think that people who download re-edits or original versions DVDs made here (SW or not), have the official releases at home (what could be the point to download alternate versions if we don't have the "official" one?). And all that is really not made for a large public...
