mates DVD recorded material on one side with 
digital audio material on the other side. Please 
be aware that the audio side of a DualDisc may 
not play on this product because these discs do 
not conform to the CD standard.
“DualDisc” is a trademark of the Recording 
Industry Association of America (RIAA).
