I admit I have never heard about or used getcap and

I ran setcap as you suggested in your additional post

<br>
Five years ago I burned several labeled "LongLife"
Verbatim BD-R DL/50 Gb discs with the same LG burner
and previous K3b/Cdrecord. When these discs became
EOL, I tried corresponding 'Mediarange' discs. These
failed to burn and Cdrecord returned an unknown error
(code 254). This error 254 is posted on some forums
with different solutions. <br>
Some said burning could be broken by some unfrienly
programs. Regarding Mediarange, Joerg Schilling
suggested to upgrade the burner's firmware, but still
no burning success with those Mediarange discs
anymore.<br>

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></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">well, hang around for 20-30 years more and we find out from your experience! :-)</div><div dir="auto"><br></div><div dir="auto">Thanks a lot for all this quite costly experimentation!</div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>

I have currently had some more success to complete
burn some unbranded BD-RE/DL discs from Slowmoose,
with less failing. The remarkable is that the disc
burn is so unstable and inconsistently, as it may fail
on the first two attemps before it succeed on the
third. Some burns may fail immediately, other not so
fun after 1 or 1.5 hour(s), or ca. 1/3-1/2 of total
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>

Many articles recommend to keep three types
of media for archiving stored on at least
two locations to spread the risk.<br>
For camcorded video this envolves for me <br>
<ol>
<li>keep the source media (tape cassettes)</li>
<li>a digitized version on portable
expansion USB3 discs</li>
<li>and on optical Blu-ray data discs and
playable BD-video discs. </li>
</ol>
