There is, and never will be, a "copy-proof" DVD.
A DVD is nothing but a megatude of binary codes which can be reduced to a single number made up of an extremely large string of 1's and 0's. This string of 1's and 0's is what a DVD player needs to know to play the movie and is also the same string of 1's and 0's needed to make an exact digital copy. Any DVD that can be played, will be able to be copied with relative ease and with the help of fast acting computer geeks, in a manner that can be made user friendly.
but the only thing the media comapnies worry about is whether that technology is easily accessible by the "masses". the average person isn't going to search the internet for software hacks and DVD player flashes, they will just swallow whatever is commercially available. if 1% of the people engage in defeating this, the media companies have achieved their goal.
