Doug Carson & Associates (DCA), makers of DVD mastering software, announced today that the first 3X DVD-ROM disc was officially mastered over the weekend, a move that some think will allow HD DVD to become more popular and possibly even win the ongoing "format war" with Blu-ray. The disc is a standard, red-laser DVD disc, but will carry higher-def content on it than standard DVDs and is only playable on HD DVD players. The disc will still support HD DVD's UDF 2.5 file structure as well as AACS copy protection. ArsTechnica
