Query: You should do some research first...

You need to do some research first. This drive only writes in the DVD+RW format on DVD+RW media. The DVD standard, ie. most widely compatible format is DVD-R, which this drive does not support. This drive of course also writes CDR and CDRW, but you can get the Sony Spressa CDRW Drive...to do that. I almost bought this drive due to the misleading marketing of these drives, but now I know.If you want a true DVD compatible burner (DVD-R), buy the Pioneer or the Philips.
