Ok here is my story, My friend tells me that the most important dvd media to buy is DVD –R because this format is the most common among dvd players. So I got DVD x copy and all my other stuff, and when I go to make my first copy, I realize that my DVD rom is a +r. I have an HP Pavilion with a DVD rom - HP 300i/NEC ND-1100A 4X DVD+R/RW. So here are my questions: Should I just burn all my backups to +R and not worry about it? Is there a driver to allow me to use the drive as a –r and or a +R? If so where can I get it and how do I upgrade it?
