That is program used from decrypting dvds so that they can be copied. It basically bypasses the copyright protection on the dvd so it can be read. So if you need to make a copy of a dvd program that is protected you need to use something like this.
DVD43, standing for "DVD for free", is free software for windows, used to assist with the ripping and converting of media, it is used with other software to actually convert, rip, and copy.
It is a free program that you can find using google. It is a program that removes the protection on DVD's to let you copy a movie with your regular burning software.
