HD DVD "twin format;" triple layer disc

[sedaku]

Well alot of dumbass have been mistakenly bought HD-DVD thinking they will be albe to run it in there DVD players.

This is just the HD-DVD camp strategy to boost more sales, target: ignorance consumer.

if they are going to offer a disc with HD DVD and DVD...they shouldn't charge more for it...

This is supposed to work in standard DVD players, but will it really? I can just see all kinds of compatiblity issues popping up.

Twin format disc can be a double edge sword. An uninformed person buys the disc thinking it's high def and then plays it on his/her DVD players then concludes that the video quality looks worse than Blu-ray because the DVD player can only read the DVD layer of the disc.

I concur, HD DVD/DVD combos are all about returns management now. Early on I think studios like Universal used them experimentally and as a cheap way to include the DVD extras without having to author them in alongside the HD presentation. It was easier to do. But, now I think they're focused on consumer misinformation. Few stores will let you return something after it's been opened. The fact that Universal is only supporting combos on day and date, not catalog releases implies this, as that's where the majority of mistaken sales are going to come from. Then there's Weinstein, who doesn't do combos, but releases HD several months after the DVD. Maybe it's just coincidence, but I think they figure the people who wait will know the difference. There's no other reason that I've thought of not to support day and date, when everybody else is.

This new disc format, like TotalHD is just a step backwards IMO. They need 4 layers to do it right - otherwise flippers are better. And it's just asking for more problems.

Meh,

Blu-ray can do 4 layers without any problems.
2 layers BD at 0.1mm and 2 layers DVD at 0.6mm.
HD-DVD can only do 3 layers because both HD DVD and DVD are at 0.6mm

Still the result is a pricier disc than its single format counterpart.

Huh!. if they could do it without any problem they would have released some by now.

Why do you say that? You're assuming they want to release some, but you can't make that assumption.

I believe the BD two layer structure is:

1.0mm substrate
Layer 0
0.25mm separator
Layer 1
0.75mm top layer

For each subsequent layer, the separator gets smaller and smaller and the cover layer thinner and thinner.

Agreed.
