I still think it's cgheaper to factory print 3 dvds than 1 bd 25.
they churn dvds out and have been for years so the cost will be low. BD is still new and not made or sold in anywhere the same quantities as DVD.

Edit: you haven't provided any proof and how is 1 bd 50 cheaper to produce than a dvd9? If it's produced the same as a cd then how are dvd's produced differently?

I'm thinking what you are saying is wishful thinking on your part.

Why are you not taking into your calculation R & D that has been already paid with DVD disc. In electronics, physical cost is usually less than the cost involve in developing and releasing the product. I agree that both of them cost maybe 10 cents of plastic, but what about the R & D already covered with DVD which means way lower royalties involve?

it is because you do know one of the most thing's that make both HD DVD and Blu-Ray was the cost/GB per layer  was cheaper due to how you have to manuf. standard DVD's when you have to go to DL-DVD9's , both HD DVD and Blu-Ray are vastly cheaper cost per/GB per layer because it's like a production like you would  a single sided single layer CD or DVD

Think about this for a sec.

CD single sided single layer = 600 an 700 MB capacity's

DVD dsingle sided single layer = any where from 1.8 GB to 4.7 GB

SINGLE SIDED SINGLE LAYER 

HD DVD 15 GB

Blu-Ray 25 GB

there is no contest BOTH HD DVD and Blu-Ray production cost per/GB in single layer single sided is chaper than even a

single DL-DVD 9

Most of the "filler" on the discs are movies. Ditch the long cut scenes in favor of in game animations and the space required for an HD game would drop dramatically.

Just because you get more GB on the disc doesn't mean it's cheaper to make.
The process to make it is more costly due to being new and needing new equipment, not as many made. More produced=less production cost.
If one BD 50 cost less than one dvd wouldn't devs use that on the ps3? but you say they stick to BD25 which you say are cheaper to produce than 2 DVD9's.
Which is it?

BD 25's R&D started since before 2003, Blu-Ray HAS Been on the market since 2003 in one shape or form.

its already been paid for , the real cost was increased upfront because you had to make newq production lines.

remember HD DVD's could be produced on  the same DVD line's but Blu-Ray's could not!

that's the point you needed a whole new upgraded production line for Blu-Ray,

though you did not have to with  HD DVD but it still is cheaper to produce those

HD DVD/15'S AND BD/25's than it does to produce a Single DL-DVD 9 on their production line's

that's the real advantage.

What your saying is true, but its a big simplification of the reality. Reality is that youlll pay a lot more royalties on a blue-ray disc than with 2 Dual layer DVD disc.

You're going to need to provide proof now. Saying the same thing over and over doesn't make it true.

lol..O'L god yes, that is an understatement unless it's (2) BD-25's but that is what the BD-50 is for.

it's a fact that not having to interrupt my gaming session to switch dics is more convenient and a PLUS than having to do it, posters that say otherwise are just delusional feeding themselves with lies.
