The answer is YES YOU CAN! Take advantage of one-touch recording from videotapes to DVD+/-R and RW discs or from DVDs to VHS tapes. A variety of different inputs also let you record from compatible camcorders, external TV tuners or cable boxes.

CONSUMER ALERT: This model does not have a built-in tuner for recording TV programs and will not record copy-protected tapes or discs. For more information, call the Federal Communications Commission at 1-888-225-5322 (TTY: 1-888-835-5322) or visit the Commission's digital television website at: www.dtv.gov.

I bought a ;magnavox dvd disc and cassette recorder combo.
I am having trouble with setup items? I get nothing on the screen to select from?

Depending on the procedure you may be pressing the record button instead of the D.Dubbing or Dubbing button. When recording from VHS to DVD you must first, load the blank DVD and VHS home movies, then play the VHS movies, then PAUSE the VHS movie when you want to START recording... then the only the you have to do is pressing the D.Dubbing button or the Dubbing button. If your VHS tapes starts to play after the Dubbing button is pressed you have been successful in Dubbing.

Hi.
I'm sorry, but according to zenith xbv323 VCR/DVD combo user's manual page 24 you can ONLY copy DVD to VCR and not the other way

Cannot do this on a combo unit. There is a chip that senses copy protection and prevents recording a copy-protected DVD to a VHS and vice-versa. Solution: Use an outboard DVD player or an outboard VHS VCR and try the recording with the video routed through a "stabilizer" box. The stabilizer (about $30 or less on Ebay) defeats the copy protection on MOST DVDs, but not all. It works with Netflix DVDs. Route the audio as usual. Audio is not protected.

The illustrations within the PDF is very help!

The disc needs to be finalized.
