BR may have sold more then HD, but their total sales is still an extreamly small number due to the fact that there is an extreamly small number of people that have the players, the correct TV, the correct cable, the correct...

I mean there are soo many pre-resequits to playing HD disk's and each bit are silly-expensive I am not supprised it aint taken off
Couple that with the Betamax vs VHS wars are fresh in peoples minds and people don't want to be bit by that, couple that with Sony's ability to come up with something technically more advanced the the competition BUT screw it over with really restrictive licencing and price I ain't going anywhere near either format for quite some time

And that is even before I have even mentioned the DRM which would effectivly tie you into a certain format. DRM isn't about stopping piracy, they big execs have even said that. It is about controlling what you do, remember you are no longer buying a product to watch, you are leasing a licence that can at anytime be revolked

Blue ray has an increased data density, and hence and increased problem with scratched discs, as with higher data density, a smaller scratch matters more. DVD is about as good as you're going to get without a protected media. Even then it's still a spinning media which means it can only be protected so much. Simply running the medi exposded it to ambient air. I'd hate to be the company that tried to sell the idea of protected atosphere shielded optical discs on a commercial scale =)

It's not 2 or 4 gig.

It's Blue ray 25 gig, HD 15GIG for single layer.
HD currently has the present advantage in that the dupilication media is compatibly with DVD which lets them do two layers cheaply.

Blueray is 50 gig, HD is 30. on double layer.

There are some experimental results with modified optics of blueray discs at 4 or 6 layers... The advantages of superbit media are that much more expanded with the increased storage space. If anyone has ever watched an action movie using compression, storage media size and read back rate are king. Even on a regular TV.

I was just throwing out unrelated numbers (as the actual number wasn't what was important) when I made that particular statement. My statement is true no matter the size. Unused space is just wasted space, whether it's 2, 4, 30, 50, or 2000 Gigs.

I just don't see it getting used. I have nearly eight-hundred DVDs in this household and I cannot possibly tell you how many, other than saying quite a lot of them, have only a single commentary as the entirety of its extra features, some even less than that. I don't see it changing much just because disc sizes are bigger. They have some extra room now and choose most of the time not to use it.

I don't see size as ever becoming a serious issue, as a factor to choose from, between Blu-Ray or HD-DVD. It's like those people who brag about having 2000 Gigs of space striped in a RAID array across four hard drives in their computer, yet they use in total less than I do on my single 350 Gig drive.

 

You must be able to copyright a number. Any program is just a large number. The hex file that you write to a pic chip is just a big number. The pdf file for an ebook is just a (very large) number.

At what point does a number become copyrightable?

Mike.

 

TekNoir, you seem to be missing the point, all that has to be done to use the space more efficiently is to tweak the codec so that it uses all the available space. At Blueray/HD capacities compression only has to be minimal which means images quality goes up. And it allows HD which is what the increased capacity is really useful for. A standard dual layer DVD can just barely hold a modern film at a good quality nowdays. Completly usuitble for HD movies.
