functions in dvd+rw-tools are a bit intimidating to the reader.
I hope it is possible to leave much of this to the drive.
And if it fails ... well, it's only speed setting. :))
ts A61229 : Burned to several DVD-RW formatted to mode Restricted Overwrite
by dvd+rw-format. Needs Libburn_support_dvd_minusrw_overW.
ts A61230 : Other than growisofs, libburn does not send a mode page 5 for
such DVD-RW (which the MMC-5 standard does deprecate) and it
really seems to work without such a page.
ts A70101 : Formatted DVD-RW media. Success is varying with media, but
dvd+rw-format does not do better with the same media.
Todo:
Determine media capacity.
Determine drive+media speed options.
Determine first free lba for appending data.
Determine start lba of most recent mkisofs session.
