Well, since this is another issue, I'll answer :) You cannot _read_ a DVD without having exchanged the CSS keys with the drive, it will return "not authenticated" when you try to read the protected sectors (ie not all sectors on a DVD are protected, there might be programs, pictures and stuff thats not). So you would need special HW to read the original, before you can copy. And yes I think the DVD guys are the bad ones, and they try to hide the real agenda, but the DVD hackers are not much better I'm sorry to say. -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
