Can NEC ND-4550A really backup a SafeDisc 4 DVD?

I asked this question after a poster said that he was able to backup a SafeDisc 4 DVD w/o emulation. No one seemed to have an answer for me in that forum.

So my question is to anyone with a NEC ND-4550A and a SafeDisc 4.x DVD. Is this the first sucker that can backup a protected DVD?
