The manpage of growisofs suggests this:
Note that DVD+RW re-formatting procedure does not substitute for blank-
ing. If you want to nullify the media, e.g. for privacy reasons, do it
explicitly with 'growisofs -Z /dev/dvd=/dev/zero'.
which is exactly what i suggested - writing 0 byte disc
dvd+rw-format will clear DVD+RW disk.
Definitely much easier.
