Whats the difference between DVD+R and DVD-R, and how can I tell the difference when looking at a disc?
DVD+R – 4.7Gb (4.38Gib), but about 6Mb less than DVD-R. Created by the DVD+RW Alliance. Technically not an official DVD format as it is not recognised by the DVD Forum. Supports bitsetting (see below). About 89% compatible (set-top devices) without bitsetting DVD-R – Originally 3.95Gb later expanded to the full size. Created by the DVD Forum (Who came up with the original DVD standard). About 93% compatible (set-top devices) Some people believe that the DVD+R standard is _technically_ a better format, but in practice it doesn’t make much of a difference, except where bitsetting comes into it. The first four bits of the disc determine what kind of media it is. DVD-ROM identifies itself as such, and DVD-R identifies itself as such. DVD+R allows you to set the disc to identify itself as a DVD-ROM to increase compatibility HOWEVER – Most modern DVD writers are hybrid, meaning they can write both, so the choice is down to what you’re going to play it on when you’ve finished They can both us
