Found in one of those links: "So while it may well be fair use for an individual consumer to store a backup copy of a personally owned DVD on that individual’s computer, a federal law has nonetheless made it illegal to manufacture or traffic in a device or tool that permits a consumer to make such copies,"
I think the sue was against the makers of a program that circumvented the dvd copy protection, not about private persons making personal copies of their dvds.
Personally I have made copies of my dvds and cds, and store them on my computer. No one should have a saying about what I do with stuff I have paid for, as long as I don't harm anyone or any company by doing it.
I would not share those copies on a public network as a torrent or similar, as it _would_ harm the producers of the movies and music I like.
