When I first started buring witn a nu burner, I was able to burn a movie at 4x in 40 minutes. Now I have a lite-on 16x and it takes 55 minutes to burn a movie of about the same size burning at 8x. I plan to buy a system with a 3.2 or 3.4 pentium processor (the one I have now is celeron 2.4). Will this bit of an upgrade help my burning speed?? My friend is able to do it in half the time and has has a duran???
