I know DVD recorders & media exist. I'll assume they let you burn movies in a not-CSS encoded format that ordinary DVD players can play. Are there no utilities that let Joe Sixpack record his own CSS-"protected" movies? One would have to choose a CSS key, but these are known, as is the CSS algorithm. If such utilities exist, why isn't duping one's self-authored CSS protected DVDs used as a defense in ongoing DVD copy-utility trials? If DVD-CSS-burning utilities don't exist, are there any tech obstacles to creating them? Any legal obstacles? (The "interop" defense is still legit, and you're not *circumventing* squat in this case.) Couldn't you use CSS+DVD players to enforce policies like "must watch this segment" which commercial disks reportedly do?
