DVD formats DVD burners support one or more of the following disc formats: DVD-R, DVD-RW, DVD+R,
DVD+RW, DVD+R DL, and DVD-R DL. (Note that -R and +R are different, as are -RW and +RW.) R discs let you
record once to the disc. RW discs let you rerecord repeatedly. DL discs are dual layer. Use R discs for broadest
compatibility; not all DVD players can read RW discs.
