"The plus formats have the same data storage capacity as the minus formats (4.7GB), but DVD+RW offers faster writing, better internal linking and support for drag-and-drop desktop files, which makes it easy to compose the contents of a disk. DVD+R is a write-once format intended to be more compatible with more DVD players, though at this point it seems to be about even with DVD-R, which remains the most compatible computer-burned DVD format."
"... the two competing technologies use different formats. No single company 'owns' DVD and both technologies have their 'champions'." See source for list of companies that support each technology (format).
Sorry for the paste job, but I couldn't rewrite it any better.

These are formats that match the kind of DVD drive in your PC = DVD +R drives require DVD +R blank discs. DVD -R drives require DVD -R blank discs. I don't know what the technical differences are, but the front panel of your DVD drive on the PC should indicate what format it is. Some of the newer drives accept both formats.
