What are the differences between DVD+R/RW and DVD-R/RW?
The main key is to use the ones that your recorder supports. Use DVD-R/W if your burner supports the DVD- format; use the DVD+R/W if your burner supports the DVD+ format. If you have a multi-format burner, you can use either one. The readability of both formats on stand alone DVD players (the kind that you connect directly to the TV) is about the same; the R formats having better compatibility than the RW formats and the newer stand alone players having better compatibility with burned DVDs than older ones.
