I have an external DVD burner. It's a Pioneer DVR111D (capable of up to 16x burning). It's in a Nexstar 2 exclosure using USB 2.0 cable. I don't know whether it is the burner or enclosure or nero settings (I have nero 7), but when I try to burn a dvd I can only select 1x, 2x or 4x even when using 16x compatible sony and verbatim discs. http://forums.afterdawn.com/thread_view.cfm/162778 info here was not able to help me - but somebody there mentioned something about a nero "high compatibility mode". Is there a mode that needs to be turned off in nero to achieve higher than 4x? And if so where is it as I can't find it in any of the settings? Any help greatly appreciated!
