Most home DVD players will identify the so-called Book-Type of a DVD disc once it is inserted into the drive. This Book-Type is present in each DVD disc's physical structure. In total there are 5 relevant settings: DVD-R, DVD-RW, DVD-ROM, DVD+R, DVD+RW. Nowadays most home DVD players can support all mentioned types, but a small number of them can't support all of them.
So in order to be able to playback discs with Book-Types that are not supported by your home DVD player, you can use this DVD Book-Type Setting Tool to change your disc's Book-Type.
In general, DVD-ROM Book-Type can be supported by all DVD players.
