    Yes, I have tested xorriso and contaced Thomas Schmitt, both with my
    old LG burner and a new ASUS burner. It turns out that the old
    burner has lost its capability to write newer BD-R DL discs. Yet it
    still manages BD-RE DL discs. The quite new ASUS burner manages my
    previous problematic MediaRange BD-R DL discs.<br>
    It is claimed to have M-disc support ("1000-year storage solution").<br>
    <br>
    According to wikipedia M-DISC (Millennial Disc) is a write-once
    optical disc technology introduced in 2009 by Millenniata, Inc. and
    available as DVD and Blu-ray discs. <br>
    <br>
    Regarding prices I have verified that Verbatim Lifetime Archival
    M-Disc are priced about 3x normal disc quality like Verbatim
    DataLifePlus BD-R DL, and > 3x prices of some lower cost discs
    like MediaRange and Primeon. I am not (yet) convinced M-discs are
    worth the high prices for normal or personal arhival. IMO I have not
    yet seen proved experience regarding longevity for normal quality
    BD-R/RE discs. Some say as low as 5-7 years, other 10-20 or even
    20-50 years.<br>

                  burning time for 40 Gb)<br>
                  <br>
                  I maybe read somewhere that som other burning programs
                  could "leave disc without "closing session" (or
                  similar?), and Cdrecord next could run into issue to
                  rewrite those discs afterwards. I know I have tried
                  also 'dd' on some discs.<br>
