As HD DVD and Blu-ray fight it out for supremacy in the high-definition video disc market, a third contender is peeking its head around the corner. As Ars Technica reports, DVD mastering software makers Doug Carson & Associates have mastered the first of a new type of disc known as 3X DVD. This newcomer to the HD scene isn’t an entirely new format. Instead, 3X DVD is more like the high-definition disc equivalent of a riced-out Honda Civic. It’s a standard dual-layer, red laser DVD with the same 9.4GB capacity as existing discs, but it has support for the same UDF 2.5 file system, AACS copy protection, and high definition content as HD DVD. The disc will still require an HD DVD player to play, and content will have to be sampled down to 720p in VC-1 or AV-C formats. 3X DVD could become a cheaper alternative to HD DVD, although Ars reckons the format simply won’t go anywhere because users will still need to invest in a relatively costly HD DVD player.
