RatDVD is an incredible and unique freeware : it can take all the features of a DVD movie and convert them into a single compressed file, which will be readable by a classic player such as Windows Media Player. All the DVD features will be preserved : menus, choice of the language, chapters, multiple video angles, multiple audio channels... Before converting your DVD, you can even select the features that you won't need (such as the Greek subtitles or the uninteresting making-of) to make your  final file lighter. You can even convert this .ratdvd file back into a DVD format.
