Just different formats. Most PC burners do both. Most standalones do one or the other, a couple do both. |

both formats are available to burn at the same speeds. but generally, a dvd burner with a 16x - burn speed is a little more expensive then a dvd burner with a 16x + speed. a lot of dvd players support both formats but most use the - format. an example of this is someone i know purchased a dvd burner with a + speed of 16x and a - speed of 4x. he thought he was getting a great deal on a fast burner. |

some dvd players will not read a - ... and some will not read a +.
Mine will read em all. The newer ones seem to do it. Although my sister has a dvd player that will not run one or the other... cant remember which one it was. |

There's a lot more difference in burner and media quality than there is in the different formats. I use an NEC 3500 and Taiyo Yuden DVD-R discs, I've done hundreds of discs for other people, no one has ever had problems playing them. |

The truth is that the two competing technologies use different formats. No single company "owns" DVD and both technologies have their "champions".
DVD-R/RW was developed by Pioneer. Based on CD-RW technology, it uses a similar pitch of the helix, mark length of the 'burn' for data, and rotation control. DVD-R/RW is supported by the DVD Forum, an industry-wide group of hardware and software developers, and computer peripheral manufacturers. The DVD-R format has been standardized in ECMA-279 by the Forum, but this is a private standard, not an 'industry' ISO standard like the CD-R/RW Red Book or Orange Book standard.
DVD+R/RW is also based on CD-RW technology. DVD+R/RW is supported by Sony, Philips, HP, Dell, Ricoh, Yamaha, and others, and has recently been endorsed by Microsoft. DVD+R/RW is not supported by the DVD Forum, but the Forum has no power to set industry standards, so it becomes a market-driven issue.
DVD-R:
Benefits: Better DVD playback compatiblity within home DVD players.
Drawbacks: Older technology and less money behind the format means that they come out with faster media and burner technology slower. You will frequently see DVD burners that will support (for instance) 16X DVD+R and only 8X DVD-R.
DVD+R:
Benefits: Faster speeds, more inovations. They typically are dual layered whereas DVD-R is not (though Pioneer has produced dual layer DVD-R discs; read: http://www.pioneer.co.jp/press/release125.html)
Drawbacks: Will not play is some home DVD players. If you know your home DVD player will play DVD+Rs then there is no reason to not use them.
Also, just for the fun of it, DVD-R is pronounced DVD "dash" R, not DVD "minus" R.

DVD+R
DVD+Recordable defines a standard for recordable DVD drives and media defined by the DVDRW Alliance. Often called "plus R", the format is write once (compared to DVD+RW wich can be erased and rewritten). The single sided discs can hold 4,700,000,000 bytes (4.38 Gigabytes at 1024 bytes to the kilobyte) with double sided discs holding twice as much. There are no dual layer single sided recordable discs. This format competes with the DVD Forum DVD-R specification
DVD-R
DVD-Recordable defines a standard for recordable DVD drives and media defined by the DVD Forum. Often called "minus R", the format is write once (compared to DVD-RW wich can be erased and rewritten).

There are, actually.

Yes, but that is the incorrect pronunciation...
