paradox0521: Plextor has at various times including firmware on ALL of its drives that block the copying of some copy-protected discs. Check out CDRInfo and other forums, and you'll find details on how to temporarily flash your drive with an older firmware to make it work.
The Plex16x is just out, so there aren't many tests yet, but I guarantee that it will function just as every other Plextor has in that area.
And no, I'm not that interested in copying copy protected stuff.
