To create a disc that's compatible with other DVD players, it must be "finalized." This process adds certain files that are needed for the disc to be recognized as the equivalent of a DVD movie. Finalizing the disc will prevent you from recording any new material to that disc, so be sure to finish creating the disc before finalizing it.
It is not necessary to finalize the discs when a DVD-R, DVD-RW, or +R disc is recorded and played with the same DVD recorder.
