Now what CloneDVD are we talking about?... Slysoft or elby?

they are the same.

"Changed: Removed confusing "Unable to locate layer break" message"

I got that message while copying the "specials"
of a 2 DVD set today, and wondered if something
got screwed up, but everything copied fine;
good to get rid of it.
(Main title DVD did not post this while copying)

The other CloneDVD is made by CloneDVD.Net
and removes CSS & Region protection without
having to add any other software,
but, there is a little bit of calculating to dowith that one so that you get the right compression and "quality"
for your copy.
Slysoft does that for you,
and it comes out clear and perfect.
