Hi,
My Plextor 708A has just successfully burned my first DVD movie on a +R disc, using Nero Burning ROM version 6.0.0.23.
Up to now I have been unable to do this with any of the previous versions of Nero 6.
(I hope that this is not a lucky coincidence, and perhaps the next burn will fail).
In case anyone is interested, I used a very cheap Ricoh, silver top, 2.4x speed disc.
Nosmo.
