This is just a rant because it bugs me that people use Dual layer and double layer interchangably. Double layer drives are available now. They're DVD+R DL. Dual layer is DVD-R DL. As far as I know there are no Dual layer drives available, though interestingly enough there may be a dual-layer rewritable drive soon. (DVD-RW DL) JVC has announced that they plan to send engineering samples to the DVD Forum for approval.
