What is 3X DVD? It’s a variant on standard red-laser DVD-ROM which uses HD DVD’s UDF 2.5 file system and (currently compromised) industry-standard AACS copy protection to offer up to 135 minutes high-definition video. However, this is not the same high-def video one might find on a studio HD DVD release: instead, it’s AVC or VC-1-encoded, 720p resolution video content. There’s no 1080i or 1080p support (although, of course, software and player-based upscaling is possible), and the 3X DVD-ROM discs are only readable by HD-DVD drives&mdash which 3X DVD-ROM proponents argue may give HD-DVD extra weight in the format war.
