/* Progress report (with Libburn_support_dvd_plus_rW defined):
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. :))
Todo:
Determine media capacity.
Determine drive+media speed options.
Determine first free lba for appending data.
Determine start lba of most recent mkisofs session.

MMC-3 seems to recommend MODE SENSE (5Ah) page 2Ah rather than A1, A2, A3.
This page is loaded in libburn function spc_sense_caps() .
Speed is given in kbytes/sec there. But i suspect this to be independent
of media. So one would habe to associate the speed descriptor blocks with
the ATIP media characteristics ? How ?
