To copy a prerecorded DVD, the best way is really to use your computer. Use DVDFab Decrypter and DVDShrink, which are both free.

There's no standalone way to preserve menus and the like.

But keep in mind what you're doing is illegal. I'm not against backing up a DVD I own, but in my opinion, copying from Netflix or Blockbuster is just wrong.

Yes, one of these devices will allow you to transfer either one of these to DVD. Keep in mind though that the VHS you're transferring would be a commercial one, so it'd already most likely be out on DVD with a much higer quality. Obviously a transfer is useful if you've got a ton of VHS tapes though.

Years ago I found a workaround that worked for me - my RCA VHS camcorder did not transmit the Macrovision.
