The only difference between DVD-R and DVD+R is which drive supports which type of media.

DVD-R recordable drives will only write to DVD-R media, and DVD+R recordable drives will only write to DVD+R media. Some of the newest drives are capable of writing to either format so be sure to check with your drive manufacturer to be sure. Once written the media can be read on most DVD recorders and players. Both are good for general consumer use, i.e., recording video, music, or images.
