unlocking DVD-zone count

I just tried a different zoned DVD on my Powerbook G4 yesterday, and got the message that I have 4 times left switching zones. Is there any way to unlock this? Maybe that's illegal, I dunno, but I will still like to know if it's possible. My brother actually just experienced his laptop pc refusing to play DVDs anymore because of he have switched zones 5 times already.

It is possible but it voids your warranty and is a firmware hack that can ruin your machine

this has no sense..
