I have entered a DVD into my Macbook and every time when i do, the screen says the regional code doesn't match. How can I change the regional code if I want to watch a movie on my computer. Please respond to me ASAP.

Modern DVD players are built with a copy-protection compromise built in. You may change the region code a very small number of times, and then it can no longer be changed, and to play a different region, you will need to replace the player.
That small number is five initially. Once you make five changes, you can not change it again.
