Hi,
would it be possible to remove some more unqualified accusations
against DVD+R and DVD+RW media:
"Note that for unknown reason, the DVD-Plus alliance does not
like that there is a simulation mode for DVD+R and DVD+RW media
nor a way to erase DVD+RW media.
DVD+R and DVD+RW only supports one write mode that is somewhere
between Track At Once and Packet writing; this mode is selected
in wodim via a the -dao/-sao option."
Speculation about the motivations of industry committees is futile.
Erasing DVD+RW, DVD-RAM, formatted DVD-RW or BD-RE is not necessary.
They can be simply overwritten. E.g. on Linux 2.6 kernels by
dd if=/dev/null bs=1M count=4480 of=/dev/sr0
The write modes of DVD+R and DVD+RW are very different.
I would state:
"Note that DVD+R and DVD+RW do not support simulation mode.
DVD+RW do not need to be erased before re-use.
wodim does not support option -multi with DVD media.
It rather expects the use of option -dao."

Urm ...
I personally think that wodim has few clue of DVD burning
other than DVD-R[W] DAO.
But i am developer of xorriso and as such biased towards the
importance of multi-session and of MMC compliant handling of the
DVD and BD media types.
growisofs is an excellent choice for all DVD types and BD-RE.
It has a small bug with BD-R which causes an error message at the
end of burning and seems to prevent success on some drives.
On the other hand its multi-session BD-R can be correctly mounted
on antique Solaris versions. (Modern Solaris is still dumb but at
least does mount the most recent session and not the first one.)
cdrskin or the "xorrecord" personality of xorriso would have the
advantage to understand the same options as wodim or cdrecord.
Their option --grow_overwriteable_iso enables ISO 9660 multi-session
on DVD+RW, DVD-RAM, BD-RE and formatted DVD-RW.
Have a nice day :)
Thomas
