A Dual Layer disc differs from its usual DVD counterpart by employing a second physical layer within the disc itself. The drive with Dual Layer capability accesses the second layer by shining the laser through the first semi-transparent layer.

More than a few viewers have worried that their dual layer discs were damaged or defective. i never seen any...did you?
