its just that, if I burn a DVD disc, I want to use a DVD-ROM than the burner itself to get the data out. And since majority of
DVD-ROM have higher support to READ DVD-R than DVD+R, I would choose a DVD-R burner anyday.
I mean would you use your CDRW burner as everyday use to play your CDs? I would buy a CDRW and a CDROM Drive so one is only used to burn the other to just play, so that the lifespan of the CDRW is a lot more.
You also have to think, for spending 200+ bucks on a DVD Burner, you want that Burner to last and pratically all manufacturers give you only 1 year warrenty on it which is quite low. Its better to spend 40 bucks to get a DVD-ROM drive to use to read a DVD-R than use the Burner. (Don't forget your everyday dirt from your Burned DVD disc used on a DVD Burner might pick up the dirt and cost you a coaster intead.
