DVD-RW
DVD-RW are usable if formatted to state "Restricted Overwrite". They then
behave much like DVD+RW. See above.
DVD-RW in state "Sequential" have first to be formatted by
cdrskin dev=... -v blank=format_overwrite
DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
"Sequential Recording" - provided the "Incremental Streaming" feature (21h) is
available.
"Sequential" is the state of unused media and of media previously blanked
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
(Command dvd+rw-format -force can achieve "Restricted Overwrite".)
The according cdrskin option is blank=deformat_sequential .
If "Incremental Streaming" is available, then sequential media are capable
of multi-session like CD-RW. (But not capable of -audio recording.)
This means they need option -multi to stay appendable, need to be blanked
to be writeable from start, return useable info with -toc and -msinfo,
eventually perform appending automatically.
Without "Incremental Streaming" offered by the drive, they are regarded as
unsuitable media for now.
Overwriteable DVD behave much like DVD+RW. "Restricted" refers only to the
granularity of random access and block size which have always to be aligned to
full 32 kB. Sequential DVD-RW are converted into overwriteable DVD-RW by
cdrskin dev=... -v blank=format_overwrite
(Command dvd+rw-format -force can achieve "Restricted Overwrite", too.)
Formatting or first use of freshly formatted DVD-RW can produce unusual noises
from the drive and last several minutes. Depending on mutual compatibility of
drive and media, formatting can yield unusable media. It seems that those die
too on blanking by cdrecord or dvd+rw-format. Perils of DVD-RW, i fear.

addressable by cdrskin. DVD-ROM drives might show ill behavior with them.
blank=format_overwrite_full uses preferrably "Full Format" (type 00h).
This formatting lasts as long as writing a full DVD. It includes writing of
lead-out which is said to be good for DVD ROM compatibility.
A de-formatting option is available to make overwriteable DVD-RW sequential:
blank=deformat_sequential performs thorough blanking of all states of DVD-RW.
blank=all and blank=fast perform the same thorough blanking, but refuse to do
this with overwriteable DVD-RW, thus preserving their formatting. The specs
allow minimal blanking but the resulting media on my drives offer no
Incremental Streaming afterwards. So even blank=fast will do full blanking.
DVD-R
The specs state that DVD-R behave like sequential DVD-RW except the capability
to get blanked or formatted. Thus they should be useable like CD-R media (but
without -audio).
Blank DVD-R media are accepted as suitable by cdrskin on my drives.
I got only a few of those one-time recordable media and no real use case.
So i prefer to start burning my DVD-R only at the end of my endeavor about
sequential DVD. There's still plenty to do with DVD-RW testing.
