Make Your DVD or Blu-ray Player Region-Free
This one is a lot of fun: You borrow a DVD from a friend, or you buy one online somewhere.
You stick it in your player.
And then, disaster strikes!
You get a message like “Region not allowed”, and the movie won’t play.
Welcome to the glorious world of Region Codes!
Sometimes, it’s possible to bypass this restriction, but it depends on your DVD/Blu-ray player.
