    Professionally Researched. (What's this?)

    DVD-R and DVD+R are two different types of DVD for your DVD burner. They aren't entirely different, but it just depends on what you want to do with them.

    DVD-R

    DVD-R discs are supported by all DVD players and can be used to burn up to about 5 gigabytes of available space.

    DVD+R

    DVD+R discs are more recent than DVD-R discs. In 2003, DVD+R demonstrated that it could double its capacity by adding another recordable layer within the DVD.

    What's the difference?

    DVD-R is generally used to burn DVDs. It's approved by the DVD Forum, an international association of hardware manufacturers, software firms and content providers. DVD+R was made to start a format in which a user could rewrite over a DVD. A DVD+R uses a system referred to as AdIP (Address in Pregroove) to help reduce error and interruptions when burning the disc. DVD-R does not have that.

    Why use one or the other?

    Both DVD-Rs and DVD+Rs have the same amount of space in single and double layer discs. DVD+R and DVD-R both do the same thing. There isn't really a difference other than the plus/minus sign that a person would notice.

    DVD players

    A note to those buying DVDs to burn. DVD players made before 2003 do not play DVD+Rs because they were not made before then. Players made afterward do, though.
