Selling the original DVD is no different from selling your car or your old sofa. You bought it, so you have the right to resell it. Selling the copy is not a right. My suggestion was that giving away a copy is also not your right, because it deprives the artist of royalties from a possible legitimate sale.
Their next claim allowed to become law of the land will be you aren’t buying the DVD but rather the right to watch it nonsense.
This will never happen, or it it did, it would be shot down by the courts. They might as well argue that you don't really own the car that Ford sells you, but only the right to drive and ride in it.
Better start reading software user agreements closer then.
I doubt it these days. The MPAA likes to play both sides of the issue, alternately stating it's licensed material or a purchased product depending on which rights the consumer is trying to exercise. They want to avoid consumer protection laws that come with a purchased product and various rights of the people that apply to copyright.
