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 A70101 : Formatted DVD-RW media. Success is varying with media, but
dvd+rw-format does not do better with the same media.

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.
Todo:
Determine first free lba for appending data.
