I know this has been asked before, but no one ever answered it right.. how do you convert a widescreen to a fullscreen?
My bad. You want to do the reverse. It may still work by doing the opposite but I've never tried it personally.
DVD X Copy Xpress has an option for full screen or widescreen. The only problem is it only makes a backup copy of the main movie. You wont get you original menus and extras.
