Wats the basic difference b/w DVD-R and DVD+R formats of a DVD?

Present day, there is essentially no difference to the user between the two types. The way the discs are recorded is the same, but the format of the recording is different. Modern DVD players will play both formats. Older DVD players may be more selective; some will prefer DVD+R and others DVD-R, and there is no way to tell in advance which one (there used to be long lists of players showing which ones will play which format, but that is no longer valid). I have one of the first DVD players made (Magnavox); it plays DVD+R but not DVD-R. My later model Sony doesn't play DVD+R.

The recording capacity is the same. Disc prices are the same. There are minor differences in editing capabilities between DVD+R and DVD-R recorders. You can get computer drives that will record both types, but home DVD recorders are either DVD+R (Phillips) or DVD-R (Pioneer). So be sure you get the right type of disc for the recorder you have. DVD-R is the official standard recognized by the DVD forum. Both formats are available in re-writeable form (DVD+RW, DVD-RW) The difference between dvd-r (pronounced dvd slash r) and dvd+r is the following:

DVD-R is approved from the DVD forum, where as DVD+R is not.The DVD forum was started by Mitsubishi, Sony, Hitachi, and Time Warner, so it has tremendous support for its technical standards.

DVD+R as i have said is not supported by the DVD Forum, It is supported by the DVD+RW alliance which is founded by Sony, Yamaha, Philips, Dell, and JP, so it also has tremendous support for its standards. Note that Sony supports both.

But Both perform about the same. hope this helps To add what was previously said, DVD-R will ususally work on an older DVD player (2 yrs +) better then an DVD+R. For longer term storage of data, DVD-R or DVD+R is better then DVD+RW as the way the disk is written is less stable and left open for additional writting.
