When a 1080p movie with DTS is like 5GB I don't think I would want to go full blown lossless Very true but surprisingly Bluray.com & Hidefdigest gave 5 stars for audio. New DTS:X™ Multi-dimensional audio; New Dolby® Atmos™ TrueHD audio Blu-print provides also a high level scripting language (BD-script) that allows for. Enjoy the best sound possible for movies, music, and TV shows with Dolby TrueHD lossless audio built into your home theater, music, movies, and other content. If you have an A/V receiver with a decoder for the new sound formats Dolby TrueHD and DTS-HD any Denon BD player will support the new audio formats.
