CloneDVD is a proprietary DVD cloning software, eveloped by Elaborate Bytes, that can be used to make backup copies of any DVD movie not copy-protected (for this reason it is often used in conjunction with AnyDVD, a tool that includes disabling such protections). 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. By moving a quality bar (or by selecting a standard optical disc format) the user can make the DVD fit its target medium. Another feature of this software is its ability to save the contents of the disc as an ISO image, or as individual DVD files (i.e. in a VIDEO_TS directory). Conversely, CloneDVD can write a DVD from an ISO image and from a directory of individual DVD files. Consequently, CloneDVD can process a folder of DVD files (i.e. on another storage medium) and convert it into an ISO image, however it cannot convert an ISO image into a directory of DVD files. CloneDVD supports DVD recording speeds of up to 18x.
