Why is BR so much more expensive then, seeing how Toshiba is changing HDDVD as much as possible to reach BR's capacitiy? You talk about HDDVD being a fraction of the cost.
The basic problem is the 0.1mm cover layer, which is fundamental to the BD physical design and the key to its high capacity per layer.
Despite what you may have read in press releases from various BD members, the disc duplicators are still having a lot of problems getting the necessary precision on the cover layer in mass production, and are thus getting lots of bad discs, and/or resorting to extremely expensive methods to apply the cover layer.
Barring some magical technological breakthrough, this will take a significant amount of time to figure out.
IMHO it is unlikely that disc duplicators will be able to make dual layer BD in commercially reasonable quantities for quite some time, most likely leaving first generation single layer BD at 25GB competing with dual layer HD DVD at 30GB.
HD DVD does not have these manufacturing problems since the processes are well understood, and yields on test production lines are already comparable to regular DVD, hence the projected low cost for the discs.
But hey, my info could be stale, out of date, or just plain wrong.
