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(). I did not exceed the formatted range
as reported by dvd+rw-mediainfo.
