DVD region codes are worthless.
Almost all computer DVD drives and most DVD players can be unlocked to play any region coded DVDs.
Doesn't that just help prove the point though?
No matter what you do, and to what expense you go, people will find a way around it.
Who did region coded DVDs affect the most?
Your regular user, not the pirates.
Having lived in the U.S. now for 6 years I have built up quite an extensive DVD collection.
If I was to move back to the U.K. all my DVD's would be useless.
I've paid for them, and I doubt they would exchange them for European coded DVD's.
Luckily enough I have a multi system/region/voltage DVD player, also a multi system/voltage television.
