They sell devices specifically for this purpose, with both a VCR deck and DVD burner in one housing.

It is my understanding that a single unit DVD recorder /VCR combo will not burn commercial tapes to a DVD disk with Macrovision. Perhaps it will burn Tivo and cable recordings.
I also was inquiring about how to the pick a scene and other features of a DVD from a VCR tape, where there are no such features.
If your DVD/VCR will copy a commercial Macrovision? VHS tape to a DVD, I think I would need the model number.
I have never had a Tivo or cable or dish, so most of my VHS tapes are original MGM, Disney, RKO, etc. tapes that I have bought over the years, some new, some used.
