WHAT AUDIO CODECS DOES HD DVD SUPPORT?
Audiophiles are well catered for in the new HD DVD format. The existing Dolby Digital [AC-3] and MPEG codecs are joined by Dolby Digital Plus (lossy) and DTS (lossy) as mandatory. Support for 2-channel LPCM, which may be used on current DVDs, is also mandated, along with the 2-channel MLP format that has been adopted for DVD-Audio. DTS HD is adopted as an option for lossless audio.
