In hindsight, yes.

This is probably CSS access restriction.
I gues
In the scenarios when dd fails, the amount that dd reads before failing varies
from to movie dvd to movie dvd. At times dd will read 400MB before failing.
A few FWIW snippets:
dvdbackup 'fixes' the dd problem
xorriso doesn't 'fix' the dd problem
xorriso has similar problem to dd
dvdbackup 'fixes'

man udevadm says:
udevadm settle [options]
Watches the udev event queue, and exits if all current events are
handled.
