How to play ratDVD files

What is ratDVD

ratDVD is a tool that you can use to compress full DVDs (including full menus, extras, multiple audio, subtitles and angles) to much smaller .ratDVD files. It was written as a way to create smaller files that can be shared on the Internet easier and also include the extra material that would usually be cut out. However, because it is able to significantly reduce the size of the entire DVD, it is also a nice backup tool. The program will also convert ratDVD files back to DVD files so they can be burned to disc and viewed on a stand-alone player. This simple playback guide will give you the easiest method to playing back DVDs you have compressed to .ratDVD files.
