We all know that writable Blu-ray Discs (BD) store a lot more information than HD DVDs. But does it really matter? When it comes to employing them in next-generation high-definition (HD) camcorders, it certainly does.




Predictably, debate over the relative capacity merits of BD and HD DVD centers on truck-and-trade prerecorded 12cm discs. Single-layer (SL) HD DVDs hold 15GB and dual-layer (DL) 30GB while equivalent BDs accommodate 25GB and 50GB respectively. HD DVD's space deficit puts its promoters on the defensive insisting that, with advanced MPEG-4 AVC and VC-1 video compression, capacity is just fine for distributing TV shows and Hollywood movies. I'll leave that one for the industry politicians to duke out, but HD DVD's inferior capacity is most certainly a drawback for writable technology uses�especially blue laser HD camcorders that will rely on physically smaller 8cm discs."
