You are able to BUY a movie? How much do you pay for said movie? Even if you go to your local store and grab a DVD off the shelf you are still not the OWNER of the property. You are LICENSED to use it within certain limitations. To BUY a movie, at least the rights to the movie, you most likely need to get a contract and spend quite a bit of money on it.
And to repeat my argument, people ignore it, - it is not your created work you do not hold any rights to it. When you pay a company for the CD/DVD to use it you also enter an agreement - no signature is requried (again refer to Don Shekely attorney). For those that say "hah i got you zomgn00btard, I don't buy, I just download it from my bit torrents"....great you are stealing. And if you think you are not, I dare you to go to the RIAA and sign in an affidavit that you download their content from torrents that are not authorized by the copyright holders. I double dare you to then put down in an affidavit that you upload those torrents to other people so they can get copies of the software. Until you are willing to do that - all your arguments are moot. - In lamens terms - Put up or shut up.
