Not sure what can be done. It's not like we can sue or anything, but unfortuanately there are enough fans who are willing to shell out $20 or more for DVDs that people like OCP and Dr Gonzo did for free. They are extrememly overpriced, and I think that just carging between$5 -- at most $10 is more than enough to recover cost. $10 to recover cost of running a table. It's ironic when pirates are being pirated. Arrrrh. Maybe a popup during the middle of the movie or just before the movie starts "If you paid for this, you've been ripped off." or "this is for fans, by fans, spread this freely, don't charge."
I know that NYC has a disclaimer on his Blade Runner HD Edit.
