CloneDVD is a powerful tool which makes it easy to copy unprotected DVDs.
You're able to choose exactly what you'd like to copy: the main movie, one or two particular special features, or the entire DVD. If this isn't fine-grained enough, then you can also cut individual chapters, or split a movie into two so it can be spread across two DVDs. And CloneDVD 2 gives you complete control over audio, subtitles and more: you're able to choose the languages you'd like to copy (if appropriate), your preferred audio encodings (AC-3, DTS and so on), audio channels, subtitle languages and more.
The program's transcoding technology will compress your selected footage to reduce file sizes, while maintaining image quality.
And the resulting copy can then be output as plain DVD files, an ISO/ UDF image, or directly to another DVD.
