Hype? Dunno about that.

They are what they say on the tin surely? Hi-Def movies on a storable physical medium.

I'm looking forward to it a lot.

The storage that blu-ray can do isn't for movies it will be geared more towards the computer industry. HD-DVD movies will be = to blu-ray in Sound and Video. Blu-ray can just record more down the line on its discs.

In essense...I can record my porn collection on 2 HD-DVDs or a single Blu-ray disc

I guess I know which way you're going.

I'm curious to know some of the rationale behind this. Are there some things about blu-ray, of which i am unaware or do not fully comprehend, that make it an unsuitable medium for home video?

I recognize this might be oversimplifying, but doesn't the fact that blu-ray pretty much trumps hd-dvd in all categories make it a better candidate for storing data regardless of its nature? i.e. what other factors would make blu-ray better for the storage of jpgs and divx files than hd-dvd, while making hd-dvd a better vehicle for the expressed purpose of delivering digital video?

None whatsoever.

Not unless you start swallowing Microsoft and HD-DVD propoganda and smearing left and right.

Again: None whatsoever. You are correct when you say that BR is indeed better in every respect. It has no real weaknesses or shortcomings to speak of, at least from a technical aspect.

Watch what you're saying.

HD DVD has got a sensor in it's technology standard, to measure the angle difference of the disc to the laser (standard in every DVD recorder). Blu-ray Disc has a mathematical algorithm to correct the errors and deviations of the data stream coming from the disc caused by a change of the angle of the disc.
You decide what's best. Apart from that, I don't see aspect where HD DVD is surperior to Blu-ray Disc... And guess what, no HD DVD fanboy ever used that argument in favor of HD DVD (about the angle adjustment).

By the way, for the technical minds among us... I was talking about spherical aberration.

Without digging into the ugly mathematics behind all this (or as my old [ancient, really], German optics professor used to say "All you need to remember is, 'De sinus of theta equals m lamda over D.") the shallower depth of the information on the Blu-ray disks and the different numerical aperture of the optics of the Blu-ray player (which makes them a bit more difficult to manufacture) significantly negates this issue.

I think you may find a few arguments here.

I'm not too sure BD-Java is superior to iHD. Disney and Apple both voted for iHD despite iHD losing the overall vote. Disney is a co-creator of iHD so it's understandable why they voted but Apple wasn't involved in iHD's creation.

I don't believe that Blu Ray's .1mm protection layer can be considered better in any way other than from within the context of enabling multilayer storage. However since both formats offer dual layer storage even this is rather superfluous. The need for a caddy or more expensive scratch resistant coating is not something that smacks of superiority as well.

Backwards compatibility of BD isn't as good as well because it's numerical aperture is so different from red laser DVD. HD-DVD has the advantage of using a single lens OPU for both and the disc structure between RL DVD and BL HD-DVD is the same.

Blu Ray has the advantages of overall storage and the capability of scaling to larger storage amounts for data recording purposes. Because the discs are bonded with two unequal halves it's a more expensive proposition to make the discs however.

With Blu Ray we're buying into a new format that gives us more storage and speed at the expense of easy legacy support. Time will tell if these advantages significantly help or hurt Blu Ray.

With the studio support advantage the market is Blu Ray's to lose but I wouldn't rule out HD-DVD. It has inherent advantages as well depending on what Point of View you look from.

Never has a truer sentence been written on this forum. I of course completely agree.
