Electronic dvd

From Knoppix Documentation Wiki

When DVD technology first appeared in households, users were simply popping DVD discs into their DVD players to watch movies — an attractive option to the then-conventional VCR. But just as compact disc (CD) technology evolved so that users could record and erase and re-record data onto compact discs, the same is now true of DVDs. With so many different formats — DVD+R, DVD+RW, DVD-RAM, DVD-R, DVD-RW, DVD-ROM — how do users know which DVD format is compatible with their existing systems, and why are there so many different formats for DVDs? The following information which comes from http://www.chinaicmart.com/ sheds some light on DVD's different flavors, the differences between them and the incompatibility issues that the differing technologies have sprouted.
