Legitimate uses for DeCSS

Tabercil writes "Interesting article at the Washington Post, which among other things points out that DeCSS does have valid uses, and that the industry's paranoia over DeCSS is overblown." A reasonable mainstream summary of all the DVD related legal hype. Interesting that the libdvdcss folks have never had a bump with the law, but instead DeCSS takes all the brunt even tho nobody uses it.

I told him that I didn't have a player, and wasn't planning to for a while until I could cobble together one of my own that would let me get around the restrictions. He asked what I meant, and e was surprised to learn the sort of things you're not supposed to be able to do (get around region encoding, the unskippable bit, back up to HD, etc.).

      Legitimate use for DeCSS? Like what? Not paying your fees and watching a DVD on Linux? Well that's illegal. Copying a DVD? Well that's illegal too. The only possible use I see would be to copy it to your hard drive *if you own the dvd* but it would be illegal to play it on an unlicensed dvd player so what's the point. Oh and just going around the copy protection is illegal too thanks to the DMCA.

      Is it right? Well I think once I buy a dvd I should be able to watch it on whatever I want, and this includes Linux. However the law doesn't look at it that way because people like RIAA and the MPAA has money to lobby for laws to make things like this illegal. Granted they probably aren't going to go after someone like VideoLAN because they are not copying DVD's, it's used as a player. I don't think that is a court battle they are willing to try yet because I think if it goes to court it will get thrown out. They are more likely to go after dvd copying programs as they are taking out more of a hit out of their profits.

      To sum up: it is illegal, but it shouldn't be. The DMCA is an evil bill and it needs to be thrown out. I for one use VideoLAN Client all the time. It's a great player for everything.

How much courage does a tape to tape copy take? It's just as anonymous too.

      What the large companies are worried about is not the level of piracy in the west where it has never been an uncontrollable threat but in the 'developing' countries where piracy is rife due to different economic circumstances, ineffective laws, poor law enforcement and corruption. It is in these markets that they are really interested because they represent opportunities for phenomenal growth.

    "all 'copyright' = greed . . . the TRUTH is that there is no LEGITIMATE use of CSS on the first place"
    Copyright is not greed. Copyright is a legal mechanism designed to encourage people to create new works of art and useful inventions. Its purpose is to get people to continue creating new works, by rewarding them for ones they've already made. This is supposed to better society.

    Copyright can be used in a greedy fashion. But kindly keep in mind that most open source and free software licenses, including the GPL, depend on copyright. Those works (the Linux kernel, GCC, Mozilla, libdvdcss, and thousands of others) have been given to the community by their authors without the expectation of monetary compensation. This is a non-greedy use of copyright.

    CSS (and Macrovision, and region coding) is used by the movie industry to attempt to control our movie-watching behavior by dictating where and when and how we can watch movies that we have paid for. That is a legitimate use in the eyes of the industry, though I'll agree that it has been misapplied.

    But those same techniques could be used in good ways; for example to protect your own privacy. Say you have a digital camera, and you make some risque films with your lover. You could then burn those to DVD and use CSS, Macrovision, and region coding to try and make sure that no-one but you and your lover are able to watch those videos. Mind, it probably wouldn't work very well -- the techniques are too well known and too easily broken. You'd be better off encoding it to DivX or Xvid and then encrypting the whole file with PGP.

    Anyway, my point is that copyright and DVD technologies are neutral: it's how they are used that makes them good or bad.

      No, the GPL attempts to control what the recipient may or may not do with the source code. Specifically, it requires (not requests, requires) that you distribute modified source code if you distribute modified binaries. There is no legal basis (though there is of course an ethical one) for this requirement if not for copyright.

      It's pretty clear that a dvd patch is a dependant work. It has no meaning aside from the dvd for which it was created, but does that make it a derivative work?
