The Nec 3500 supports dvd-r writing up to 16x (16x, 13x, 12x, 8x, 6x,
4x, 2x)
With growisofs the drives writes correctly at the selected speed (tryed
8x, 6x, 4x)
Here is the output of cdrecord-Prodvd -prcap (that, btw is incorrect,
but it lists 4x as a choice, and I remember you from the previous post
that cdrecord-ProDvd always writes at 6x ..)
