copy protection, does work.
it keeps a lot of people from copying these disks.
the people who search for alternatives, and know some "adresses" on the net, are mostely more experianced people.
you don't have a clue how mutch people just know of kazaa. and are spending 2 whole days on downloading a movie.

it does work, but not for anybody.

Carpe diem, quam minimum credula postero
