Any encrypted cipher can be "foiled" by brute force - you're just
looking for a key.
When it is doable in a relatively short time, it's broken. Not
circumvented or broken "into", no magic bullet, but might as well be -
even if you can't derive the key, if you can run through all
possibilities, then what's the difference? You can get the key, and
systems built on this are houses-of-cards. Hence, AES, 3DES, etc.
So, our boy got a PowerDVD software key to then expose the DVD title &
volume keys and such. And this is impossible for other players, how?
Yawn.
