actually what was said is correct and incorrect about dvd copy protection.
or maybe i should say correct but a little information was either left out
or not known. there is a key protection on the cd itself that protects the
data, then you are correct about there being macrovision, but it is not
implimented on the dvd itself, it is forced on the users inside the players.
There are several players out there that you can disable these on, some of
the most popular ones are apex models. anyway like any other copy
protection out there you can get around it and the mpaa and riaa do not like
it but hey that's life. anyway hope this helps out or at least makes life
easier for everyone.
