For me as an application programmer all talk about system,
firmware or hardware is rumor. One learns to live with that.

But why did the media work in september 2004 and die a quick
and reliable dead in november 2005 ? The same spindles. Two
brands with two different media infos. Wether unused previously
or re-written. I made exact lab logs in 2004 because those are
donated media and i wanted to use them for proper science.
They were not flawless but most of them worked. Now they are
Either my burner goes bad (and there is no indication with DVD+RW
or CD-RW), or the media went bad at normal room temperatures,

One remarkable point with DVD+RW media is that all brands
of 4x media which i ever bought are reported as
Media ID: RICOHJPN/W11
whereas three DVD-RW brands yielded three media ids.
What, for example, shall i think of a warning sticker on
the wrapper of TDK DVD-RW media labeled as "2x"
This product is intended for use only in 4X speed
and further in small letters on the backside:
"Use of this product in certain [...] DVD-RW drives [...]
may result in damage to both the loaded disc and
to the drive [...] the lense [...] becomes fogged [...]
source of the problem is a firmware bug [...]"
No list of endangered drives, of course.
(Calm down, Thomas, don't be unrelaxed ... om mani padme hum ...)
The variety of cooks seems not to be conducive to the
DVD-RW broth. Let me hope the RICOH DVD+RW production plant
never burns down.
This is my impression as user and as provider of support to
other users. I got no insight into the commercial or technical
reasons of that mess.
If i get asked about what burner to buy, i answer that i got
good experiences with my current one and DVD+RW. Of course i
do not state that -RW and other brands would not work.
I do state, though, that DVD burning is by far not as technically
mature as is CD burning. A matching combination of drive and
media is still a prescious thing.

That was not my intention.

My apologies. Meant was:
if they are in the state which the documentation of dvd+rw-tools
refers as "restricted overwrite" but which is not mentioned or
used by cdrecord-ProDVD.
It is simply that growisofs is the only program known to
me that allows this burning procedure which resembles +RW
and obviously not only saves the time to blank but also
seems to save the life of my remaining DVD-RW media.
My original sentence might be a daring shortcut but is it
really misleading from the viewpoint of users ?

To my defense i ask you to consider that the specs of

Furthermore i promise to be more exacting. On the risk
that my mails get even longer.
Have a nice day :)
