Input:
My son bought the Audiovox DVD1500 portable DVD player in early November 2001.  He doesn't use it very much and takes good care of it.  He even has a padded bag where he stores it when not in use.  We have had to send this product back to Audiovox in New York twice; Nov 26, 2001 and Mar 18, 2002 at our expense...The first time the DVD player would not play at all, which Audiovox was prompt ( approximately 3 weeks) in sending us a new DVD player, and the second time because the picture would not show up on the portable screen, although we could hear the sound.  Audiovox promptly (within about 3 weeks) returned the DVD player to as with a note that they could not find anything wrong, but they cleaned it.  It currently is working, but I would rather have received a refund the second time.  Buyer beware.
