This may be old news, but here goes anyway:

DVD is picking up speed and storage capacity--but format wars and high prices may mean a wait for the most advanced new technologies.

Just when you think it's safe to go out and purchase a DVD burner, new technology shows up--three kinds in this case. The most innocuous new twist is 12X recordable--a speed jump that will save time but otherwise won't rock your world. Contending for the earthshaking technology award are soon-to-be-released dual-layer, double-capacity DVD+R and a still-over-the-horizon product based on blue laser technology called high-def DVD. Blue laser promises massively greater capacity and faster speeds, but as is usual with DVD, a war is brewing over the high-def format.
