DVD43 is a DVD de-crypter that removes the region and restriction garbage on DVDs upon reading the DVD. It presents a clean DVD to whatever video program you are using to watch the DVD. This means that your laptop doesn’t complain when you stick a DVD in it from the wrong region!
I totally do not understand why region codes exist at all. The whole notion seems insane to me. I buy a DVD and then I can only play it where I bought it? And to get around this, all one needs to do is buy a second player? How is this supposed to protect the companies licensing rights? It’s as if some lawyers set out and wrote some license for some material and then ordered some technical person to create something but with no regard for how things get used in real life. Region codes are totally pointless, easy to get around, and only hurt consumers and producers alike.
