here is a good explanation by Amir
I can see why blue ray discs will cost more to replicate.
God help bluray owners if ever hddvd went belly up
It would mean no competition and prices would go up I am sure.
here's Amir's reply
For HD DVD there is zero constraint. HD DVD lines are same as DVD lines and are able to crank out titles at the same massive rate. There are many, many replicators around the world who are already producing HD DVDs. Indeed, any modern DVD line that you buy is liable to be able to make both DVDs and HD DVDs.
BD of course, is no where close to above. Its lines can only make BD. And while some independent replicators have produced BD-25 discs, their yields and cycle time (how long it takes to make a disc) sharply lags HD DVD (even Sony claims cycle time of 4+ seconds compared to 2.5 for DVD/HD DVD). BD-50 is much more problematic with Sony/MEI the only two producing them although others are trying to get online. But even if they do produce them, the yields and cycle time are in a different class than what is needed for true mass production.
Having said all of this, the market for BD products is really small relative to DVD. So BD has not yet faced this issue head on. However, if they want to meet their grand forecast, they might face issues here with BD-50.
300 new titles this year for each format is likely to max out the available capacity.
Not for HD DVD. We could produce 30,000 titles and it would be no big deal. Note from above that if more capacity is needed, new lines can be purchases which can produce both HD DVD and DVDs (you can switch between them in as little as 5 minutes). So the investment is very protected.
BD however, requires dedicated investment in new lines so it is much riskier for replicator to spend the money. As such, if demand picks up, they may have issues scaling.
Now, before Talk or whoever jumps on these comments, I like them to produce exact figures for their yields and cycle time, as verified by independent replicators - not their own claims.
How are both camps to cope if the formats gain mass market traction this year?
Per above, we are ready and fully capable, worldwide, to meet increased demand. There is no issue here of asking one or two companies to make discs for you, and certainly you don't have to deal with your competitors to do so as is the case with BD.
I thought I was wrong once but I was mistaken
