According to Andy's text i assume that the media
was formatted automatically and thus would at
most be written at half its nominal speed.
But the reported performance was less than one
third of that half. Still very mysterious.

That's what i read from the text.
(I have my own burn programs to test. Thus i
use them at any occasion i have with BD media.
One year of BD burning strengthened my opinion
that at least my drive and my media work well
with full nominal 2x speed.)
I would omit the -speed option and let growisofs
negotiate that with the drive. Afaik -speed is
rather intended to slow down poor media.
Have a nice day :)
