"If this is true, it's Beta vs VHS all over again and HD-DVD may be the foregone winner of the format wars. First, Heise reports (summarized from the German by sgknox.com) that Digital Playground, who were committed to Blu-ray last year, are now producing HD-DVD titles instead. No Blu-ray disk manufacturer would make their disks because Sony doesn't want porn on Blu-ray (just as with Betamax). Second, as reported by tgdaily, the porn industry overwhelmingly favors HD-DVD because it's much cheaper and easier to produce. As noted in the tgdaily article, porn was a huge factor in VHS winning the VHS/Beta format wars even though many people don't like to acknowledge it. Porn, like gaming, pushes tech adoption."
