DVD + HD DVD three-layer disc

This is incredibly awesome. They've combined a DVD layer and two HD DVD layers on a single disc, so it can be played in both an HD DVD player (in high definition) and in an ordinary DVD player or computer drive. This means they can manufacture HD DVDs that are backwards compatible for people who don't yet have an HDTV but want their movies to be high-def when they upgrade. What's more is it's still very cost-efficient (much more so than Blu-ray discs.)

Wicked.

>>4 is speaking the truth.
Both are expensive and have a low tollerance.
Now if they just had stuck with the original idea to have the disc in a protective case.
