In "Reauthor" mode, the interface allows the user to choose specifically which DVD elements (Main Title, Menus, audio tracks and subtitles, and Special Features) to retain on the "shrunken" DVD; the Menu clips are stored in folders and some of them are playable. The compression is automatic if the Main Title only is selected, to fit it onto the selected size of DVD. If Special Features are also selected, their compression may be manually selected at the minimum possible using the Custom Ratio option, to give disk space to the Main Title.
