Hello,

my sister just bought her computer but yesterday i was at her place and noticed one thing on her dvd rom.. it was written dvd+-rw and i spent hours in trying to understand what it really means?

ive never understood the meaning of these acronyms and if anyone could explain me please?

does it mean that the dvd rom can read and write on dual layer discs?

Configuration: Windows XP
Internet Explorer 7.0

No its doesnt mean that.
Basically DVD+R is a dvd disc that allows multiple layers for one disc where as dvd-r only allows one layer. They will not compete to become the de Facto standard, because they are both here to stay. Multi layer DVD+R can allow extra capacity per disc than DVD-R hence its high cost!
