                              These failed to burn and  Cdrecord

                              Some said burning could be broken by some

                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>
