A:AnswerI don't think so. The manual states various CDs but does not state DVDs. Manual states that only CD formats supported. I have no DVD music so I cannot say if the unit will play them.
A:AnswerIt means the item was returned or a display item. Mine only had a couple of barely noticeable scratches on the top. It had the original box and accessories.
A:AnswerSince Onkyo has pulled out of the US marketplace, I suspect that it will not be back in stock as a new unit. I got mine as an "open box, Excellent" unit - and it was as good as new. You can find it as new on Amazon, but its price there is exorbitant - far above the suggested retail price.
