dvd+rw-booktype changes the book type field recorded on DVD+R and DVD+RW media. The book type is what a player reads to decide which kind of disc it is holding, so it directly affects playback compatibility.Presenting a DVD+R or DVD+RW disc as DVD-ROM makes many older standalone players and set-top boxes accept it, because those units predate the DVD+ formats. A specification flag chooses the identity to write; a target flag chooses whether it applies to the loaded disc (-media) or becomes the drive's default for future burns (-unit and its variants).Running the command with only a device argument prints the current drive and media settings without changing anything.

Not every drive supports book type modification, and support often depends on the firmware. Changing the book type of a DVD+R disc is a one-way operation: the field is written into the disc's control data and cannot be rewritten. DVD+RW media can be changed repeatedly. The command does not affect DVD-R/-RW media at all.

dvd+rw-booktype is part of the dvd+rw-tools package, developed for managing DVD+R/RW media on Linux. Booktype modification became important for compatibility when DVD+ format competed with DVD-.
