". . . Netflix said that as of now it will purchase only Blu-ray discs and will phase out by roughly year's end the alternative high-def format, HD DVD, developed by Toshiba. . . ."
Netflix is being very stupid -- dropping HD DVD before all HD DVD titles are available in Blu-Ray!
The smart way to transition would be to eliminate HD DVD titles where they have the Blu-Ray version in stock and stop buying new HD DVD titles only when it's clear those titles will soon be available in Blu-Ray, but it is very very stupid to drop exclusively-HD DVD titles that are already in their inventory before customers have stopped renting them.
Stupid corporate decision makers! I bet they are more concerned with fast delivery than in giving customers the titles they want in high def. Sometimes delivery speed just isn't that important. It's amazing how bad assumptions like that make they drive customers away to on-demand cable.
