It goes something like this: "THE MOTION PICTURE Association of America (MPAA) has persuaded authorities in the kingdom of Norway to try a teenager three years after he watched DVDs on a Linux computer using the Linux-based de-scrambling program DeCSS. Which he created."
I don't remember the full story, but I think it went something along the lines of the kid had to write the DeCSS program to remove the CSS encryption from his DVD and rip it to his HDD, so that he would watch it under Linux where there was no DVD playing software with CSS decryption built in. But then don't quote me on that.
Admittedly, I am not in full possession of the facts here, but it looks like witch-hunt after witch-hunt on the part of Hollywood, Record Companies, RIAA, Federation Against Copyright Theft, etc, etc, etc... these days.
