There has been plenty of debate between two empty DVD disc which are available in the market. One is the DVD+R and the other is the DVD-R. Plenty of myths have been circling around on which is better, but here I am to say that they have no difference apart from their developer and who supports which disc.
DVD-R/RW was developed by Pioneer and is hugely supported by the DVD Forum, an industry-wide group of hardware and software developers, and computer peripheral manufacturers.
