Ha! This is sweet – and exactly what I speculated on after the HD-DVD announcement. I guess they *can* put BD content in front of DVD content. Isn’t light great? And this gives them a leg up on HD-DVD. Why the HD-DVD/DVD hybrid is basically a dual-layer DVD physically, with one DVD layer and one HD-DVD layer, this is a full dual-layer DVD *plus* BD. The HD-DVD/DVD can only hold 15GB HD and 4.7GB DVD – this disc can do 25GB HD and 8.5GB DVD. So studios wouldn’t have to compromise – most releases today are on DVD9, not DVD5. With the HD-DVD hybrid they’d have to turn up the compression and/or make very bare-bones releases. And JVC is working on a 50GB/8.5GB version – so there’d be *no* compromise on either side. Full dual-layer HD and full dual-layer DVD.
I think this is just one more way in which BD is superior to HD-DVD.
