Burning DVD-Video with DVD+RW/DVD-RW

It is possible to burn a DVD-Video with rewritable using Nero, and not make it final?

When I go to DVD-Video in the New Compilation Screen, under the burn tab, Finalize DVD is checked and greyed out.

I was under the impression that it was possible to burn an erasable DVD-Video, am I mistaken?

What is the problem with finalising it? You can still erase the RW.
