and I also found this at http://fy.chalmers.se/%7Eappro/linux/DVD+RW/:

"It was observed that excessive reformats can render media unusable
already after 10-20 reformats. It appears to be a firmware deficiency,
not some common media defect [at least it was perfectly possible to
salvage the media in a unit of different brand], but I don't recommend
[enforced] reformat in either case. Note that DVD+RW re-formatting
procedure does not substitute for blanking. If you want to nullify the
media, e.g. for privacy reasons, do it explicitly with 'growisofs -Z
/dev/scdN=/dev/zero'. Otherwise just write over previous recording as
it simply wasn't there, no re-formatting is required.

DVD+R media does not require any formatting procedure applied and is
ready to use out-of-the-box. Apparently, a reminder that 1st
generation units (Ricoh MP5120A and derivatives) are not capable of
burning DVD+R is needed."
