Preserve the complete DVD structure
A structure-preserving backup keeps the DVD file system, titles, chapters, menus, audio, and subtitles together instead of re-encoding only the main feature. Choose a DVD folder or ISO when those navigation features matter.
Confirm that you are authorized to copy the source, select an output location with enough space, and keep the disc until the backup has been mounted or opened. Verify menus, title order, chapters, audio languages, subtitles, and playback from beginning to end.
