Thank you, once again, Thomas.
I've noticed I omitted to post the command line:
xorrecord dev=/dev/sr0 -v padsize=0 -multi fs=64m blank=format_overwrite Disc01.iso
I hope I'd followed your recommendation correctly.
I am far from unhappy with the writing speed. Considering it has taken
me a year to accumulate enough data for a couple of BD-Rs, this is far
from the most important aspect of my life to begin optimising! (I got
the BD writer to save time versus writing multiple DVDs, but, thanks to
my stupid oversight with the USB port, it may now be several centuries
before I have a credit balance.)
As long as writing speed is reasonable, what is important for me is the
quality of the recording; any time spent backing-up is waisted if you
can't recover the data from the media when you need them, of course.
I am considering having a go with cdck (I hope hearing about that
doesn't send its developers into hiding), but I wonder how much this is
verging on paranoia. I burnt a second copy of each ISO, which should
give me a high probability of full recovery using gddrescue, if the time
comes.
By the way, I THINK I noticed that, during the formatting stage, each
successive status line reported progress as 1%. Not really an issue, as
the formatting completes before I have time to worry.
Best wishes for an idiot-free future.

Bug description:
Note: libburn 1.3.8 (Ubuntu 15.04 AMD64)
Confident of correctly observing the symptom (in four / four tests
with BD-R 25 GB), but apologise for pointing a finger that may be
stabbing in the dark.
