I have an older LG drive which I use with Win ME so I am not familiar with use with XP. The beauty of DVD RAM is that you use it like you use a floppy (if you can remember them). A format utility should have been provided with the drive (if not you can download the software). You format a disc then you use it like a very high capacity floppy. No special software (Nero, XP's own etc) is needed to write to DVD RAM discs. You just copy or save to the disc as you would to a floppy or harddrive.
This drive also supports DVD+/- and you use Nero to write to these formats.
