HJ, you're missing the point.
When you purchase a DVD, you are not purchasing the rights to the movie. You are purchasing the disk.
If you want to use that disk as a coaster, or a frisbee, that's your right, you own that disk.
You do not own the rights to the data contained on it.
When you purchase that DVD, you are essentially purchasing the ability to view the movie.
Uh, No.
You are confusing SOFTWARE LICENSING with COPYRIGHT.
I can take a DVD and copy it and make edited copies or even pay someone to do that for me for my own use to my hearts content without any violation of any COPYRIGHT.
COPYRIGHT is exactly that RIGHT TO COPY, the owner is the only one allowed to COPY IT FOR COMMERCIAL USE... Once I own it I can do whatever I want with it for my own use.
I can take a book, and pay someone to go through it with a black market and make parts of it unreadable if I want to.. I haven't violated any laws.. I can photo copy every page and staple them together in the wrong order for my own use IF I WANT.. I have NOT violated any copyright laws.
