/* DVD/BD progress report:
ts A61219 : It seems to work with a used (i.e. thoroughly formatted) DVD+RW.
Error messages of class DEBUG appear because of inability to
read TOC or track info. Nevertheless, the written images verify.
ts A61220 : Burned to a virgin DVD+RW by help of new mmc_format_unit()
(did not test wether it would work without). Burned to a
not completely formatted DVD+RW. (Had worked before without
mmc_format_unit() but i did not exceed the formatted range
as reported by dvd+rw-mediainfo.)
ts A61221 : Speed setting now works for both of my drives. The according
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.
ts A70112 : Support for writing to DVD-RAM.
ts A70130 : Burned a first non-multi sequential DVD-RW. Feature 0021h
Incremental Recording vanishes after that and media thus gets
not recognized as suitable any more.
After a run with -multi another disc still offers 0021h .
dvd+rw-mediainfo shows two tracks. The second, an afio archive
is readable by afio. Third and forth veryfy too. Suddenly
dvd+rw-mediainfo sees lba 0 with track 2. But #2 still verifies
if one knows its address.
ts A70203 : DVD-RW need to get blanked fully. Then feature 0021h persists.
Meanwhile Incremental streaming is supported like CD TAO:
with unpredicted size, multi-track, multi-session.
ts A70205 : Beginning to implement DVD-R[W] DAO : single track and session,
size prediction mandatory.
ts A70208 : Finally made tests with DVD-R. Worked exactly as new DVD-RW.
ts A70306 : Implemented DVD+R (always -multi for now)
ts A70330 : Allowed finalizing of DVD+R.
ts A80228 : Made DVD+R/DL support official after nightmorph reported success
in http://libburnia-project.org/ticket/13
ts A80416 : drive->do_stream_recording brings DVD-RAM to full nominal
writing speed at cost of no defect management.
ts A80416 : Giulio Orsero reports success with BD-RE writing. With
drive->do_stream_recording it does full nominal speed.
ts A80506 : Giulio Orsero reports success with BD-RE formatting.
BD-RE is now an officially supported profile.
ts A81209 : The first two sessions have been written to BD-R SRM
(auto formatted without Defect Management).
