The main advantage of ratDVD is that it allows a whole DVD complete with menus and all bonuses to be compressed by a factor of three - minimum. You can see some results at CDfreaks. It therefore allows people to store more than 100 full size DVDs on a desktop hard drive. Also of interest is the option which allows you to convert a ratDVD back to a normal DVD which allows you to view it on a stand alone player.
