You can't rely upon "Disc status" or "Number of Sessions" values
returned by DVD-ROM unit.

But you can tell if DVD-ROM unit managed to recognize extra session by
examining "FABRICATED TOC."

Once again. It's not OS which does most magic, but the unit it [OS]
talks to.
> FABRICATED TOC:

Most notably "Multi-session Info" would be different if your unit
supported DVD+R multi-sessioning. You would also see at least one extra
track.

Well, by the time I wrote "DVD+R burners will be the only ones capable
to access the files added at different occasions" on my page, there were
no DVD-ROM players available capable of multi-session playback. Now you
indeed can ran into one, so I've modified the statement as "your DVD
burner might be the only one capable..."

Yes, this flag refers to CD multi-sessioning capability and it does not
imply DVD multi-session capability.
Bottom line. DVD-ROM unit in question is simply not capable of DVD+R
multi-session playback. A.
