Requantizing only compresses the video stream, leaving the audio and subtitles unchanged; this means that the process only affects the picture quality. There are two compression modes you can choose from, either Full Disc Copy mode, which compresses the entire DVD such as
24 Seasons 1-8 DVD boxset , keeping menus and extras, and there is Movie-Only mode, where you select a feature, or set of features you want from the DVD like
Doctor Who Seasons 1-6 DVD Boxset , and it will discard the rest, including the menu (the feature will just start playing when you insert the DVD). If you want the best quality possible, Movie-Only mode is the way to go. If you want to keep the menus and special features, and don't mind the image quality degradation, then Disc like
Family Guy Seasons 1-6 DVD boxset Copy is the mode for you. For the purpose of this guide, I will tell you how to do this with DVD2OneX 2.x as that is the solution that gives the best results, but the same principles should apply to the other programs, and their interfaces shouldn't be too hard to figure out.
