a + and a -. hehehe I couldnt resist. To tell you the truth I dont know either, except that they are new formats for reading and recording dvds. I dont think one is better than the other, merely a different flavor to make more money and frustrate copying. Pending upon who previously recorded the format chose either + or - which makes you follow suit for copying. Last time I was in the Local Comp "rip you off" USA my mind began to get twisted at the plethora of DVD and CD-R packages that claimed this, that, or the other to buy. To me its all about squeezing the buck rather than the improvment of quality that we are lead to believe.
Basically, there are different formats based on the manufacturer - pressed/manufactured DVD ROMs should be readable by any device, but the read/writeables are format specific. Later DVD burners can read and write in multiple formats.
Its no sure bet if and when one standard will emerge. If I was buying and planning on sharing disks with others, I'd be buying a multi-format drive.
rember when you had to choose your video recorder to be either a BETA or VHS and eventually VHS won even though BETA was a better format, same here just 2 different recording means. Don't worry however as the latedt DVDRW are both + and - and cost less than ?50.00 probalbly cheaper in the states if that iswere you are.
