I recently bought a Panasonic

Question

I recently bought a Panasonic DVD Recorder, model # DMR-EZ47Vand can't change the screen aspect on a wide screen editionDVD on a standard 4:3 television set. I spent $99.00 for a Circuit City tech to come to my home and tell you can't doit on none wide screen TV set. I found nothing in the manual that says you can't. Is this true?
