"Actually MeBeJedi, that’s not entirely true. There are several companies at the moment which take movies and edit out “offensive” content. They then take those modified DVD and ‘rent’ them back to the constitutents who are part of their lending library, so to speak. Yes that might sound a lot like selling an altered uncreatively editted movie but for some reason they can get away with it."

I know what you are referring to, and last I heard, all the movie companies, and the directors of said films, were banding together to fight this in court. They may be "getting away with it" for now, but that doesn't mean it's legal, or that it's going to last.
