DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state

"Sequential Recording". DVD-R are always in sequential state.
"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.
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.)
of multi-session like CD-R[W]. (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, only write mode DAO is
available with sequential DVD-RW. It only works with blank media, allows only
available with sequential DVD-R[W]. It only works with blank media, allows only
one single track, no -multi, and demands a fixely predicted track size.

blank=deformat_sequential_quickest is faster but might yield DAO-only media.
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.
