Story: Double-layer DVD heats up standards battle

Hi,

Regarding double layer technology, most of people overlooked key point that is compatibility with existing DVD players and drives. Since firmware needs to be upgraded, technically most of existing DVD players and drives CAN NOT READ the disc written by double layer technology. Imagine, you buy Sony’s double layer DVD drive, which is $50 higher price than normal drive, and double layer 2.4X+R disc, which is Yen1,500 in Japan (equivalent to$12.5 per disc!). You’ll record your family video image on the double layer disc and take to your DVD player in living room. Then very likely your DVD players CAN NOT play the disc!! Manufactures don’t mention about this problem but this is already common knowledge in the industry. For a while after launch of double layer technology, it’s useless at least for consumers.
