CloneDVD is a proprietary DVD cloning software, developed by Elaborate Bytes, that can be used to make backup copies of any DVD movie not copy-protected. The program is able to transcode a dual layer DVD movie to fit it onto a DVD-R, DVD+R or DVD+R DL (Double Layer) disc. Users also have the choice to strip audio streams, subtitles and chapters. This is called customize. For example, users can edit and delete certain parts of a DVD that they don't want burned, such as the main menu, bonus features, commentary, or certain scenes from the actual DVD. By moving a quality bar (or by selecting a standard optical disc format) the user can make the DVD fit its target medium.
