Understanding the disc structure Karaoke DVD Burner allows you to create a DVD disc with a menu and submenus that make selecting songs much easier. There are two ways you may arrange the songs on the disc:   1. Use flat directory structure ( Create folders option is not selected) The DVD disc created with this setting will have only one level of menus, containing all songs. If the songs do not fit on one page, subsequent menus will be created and navigation buttons will be added to the menus.                 2. Use folders to organize your songs ( Create folders option is selected) Songs are organized into folders. The root menu of the DVD disc will contain the folder list (it may span several pages if necessary) and menu items will lead to submenus with the actual songs. This allows you to arrange songs alphabetically, by genre, or by the karaoke disc they came from. Menus are created automatically and navigation buttons are added if needed.                 The only limitations are the total number of menus (99) and the disc size (it should be possible to fit up to 300 songs on a single DVD disc).
