As I don't think you have been clear on this point yet...is your *_MEDIA_* DVD+RW or DVD-RW, or one of the DVD+R or DVD-R variety? The following links may be of some use for an attempt at "blanking" the disk before reuse. DVD+RW http://www.freebsd.org/doc/en/books/handbook/creating-dvds.html#AEN25355 DVD-RW http://www.freebsd.org/doc/en/books/handbook/creating-dvds.html#AEN25401 it looks like, from my quick read, DVD-RW may need an explicit blank before reuse Of course the source of growisofs may be of use http://fy.chalmers.se/~appro/linux/DVD+RW/ -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter
