Emerson Radio Corporation Dora The ExPlorer DVD Player

My daughter received the Dora DVD player and Matching TV for Christmas last year. After about six months the DVD player quit playing and would display "NO DISC". When it was working, it ran really loud and got really warm to the touch. I finally got around to calling the company and the customer service recording said "if you purchased a Dora or Spongebob DVD player, please hold. if you are calling about a different Emerson product, please call ###-###-####". They have a line just for this DVD player, apparently there is a problem with them. I barely had a chance to tell the girl what the problem was with it and she said "you'll have to send it in for repair or replacement, it's still under warranty." I explained that I didn't have the receipt and she said that's okay. Most of them were purchased around CHRISTMAS last year and the warranty lasts for a year. I sent the DVD player off to the address in Irving, TX and am waiting to see what happens with the next one they send me, although knowing that I am not the only one with this problem, makes me worry about the quality and safety of this product, especially since it is electronic and electronic products not working properly could be a fire hazard.
