Video Standards


Video Standards

You cannot mix different standards easily on one DVD. The main video / movie would have to be doubled. It's hardly ever done. A separate DVD must be made for each standard. However a single DVD that has region restrictions turned off may be played anywhere in the world on a computer. Each video standard requires a separate version of a DVD and separate versions of menus must be made.
