Devil's advocate: even if you buy your DVD at Amazon you still cannot show it for $2 each to 50 people at your home or make copies for profit. Is that actually the case? Last time I sawy anything about this the publishers were trying to have it both ways, saying that on the one hand what you owned wasn't the disk it was a license to the content so you couldn't just do whatever you wanted with it, but if you tried to use that to say "well then I can rip the DVD and copy it somewhere else" you'd get an argument about only owning that specific format.
