Lossless surround sound formats
The newest high-resolution surround formats, Dolby TrueHD and DTS-HD™ Master Audio, offer up to 7.1 discrete channels of lossless audio. Along with adding two extra rear channels to the standard Dolby Digital and DTS formats, Dolby TrueHD and DTS-HD Master Audio discs are encoded with more audio information per channel. In fact, it's identical to the movie studio's original master. That means the improved directionality and more precise effects makes it even closer to the experience of being in a movie theater.

Additional discrete 7.1-channel surround formats
You may find that some Blu-ray discs are also encoded with other discrete 7.1-channel surround formats. Dolby Laboratories and DTS developed Dolby Digital Plus and DTS-HD (High Resolution), respectively. These formats deliver 7.1 independent channels of sound. They provide more detailed surround effects than 5.1 Dolby Digital and DTS, though they aren't lossless like Dolby TrueHD and DTS-HD Master Audio. Receivers that support lossless 7.1-channel formats will also support Dolby Digital Plus and DTS-HD (High Resolution).

That is what my understanding is of how the Newest Audio 7.1 formats work.
That is why I have the 7.1 (4-Subs) in my HT to catch all the surround effects on the New Blu-Ray 5.1 & 7.1 audio.
Looking forward to hearing the difference in my now out-dated Pre-Amp Integra processor to the new Integra DHC-80.3.
