    Are there any dvd's encoded w/7.1 yet? If so, which titles?
    I guess, soon the studios will be 're-releasing' movies in that format.


    thanks,
    bruce

    FYI, any "7.1" amps you see are simply taking the existing centre rear channel and splitting it into two, which is mainly on THX-spec amps (it's a THX requirement for EX/ES playback). This also true for most cinema EX/ES installations as well.
    Unless I'm very much mistaken, and there's a new format out in the States on dvd that hasn't made it to Britain yet, there's no such thing as 7.1 dvds. But I could be wrong. There is an eight-channel cinema sound format, Sony's SDDS, but this has not (yet!) been released on any home video formats. High-end Yamaha amps can also drive an extra pair of fronts specifically for the company's own DSP sound enhancements, but this doesn't need specially encoded software.

    Sony has publically stated they have no intention of bringing SDDS to the home. It's already too crowded with DD/DTS

    There will not be anything other than DD EX/DTS ES for a VERY VERY long time to come

    DVD permits up to eight channels of PCM information, although there are no DVD players equipped with the necessary internal processing to implement this, and of course no software. Considering the space this soundtrack would consume, we will never see them on DVD-Video.

    MPEG came the closest to actual 7.1-channel sound on DVD, and there are domestic processors (Meridian make several off the top of my head) available that will actually output true 7.1 (five front, two rear plus LFE; the same configuration as SDDS-8) if they ever come across an MPEG 7.1 soundtrack. Again, there is no software, but these systems are otherwise ready to go 7.1 today.

    10.2? You gotta be kididng me. What you gotta hang yourself up in the air and place a couple of speakers below as well? Yeah! Why don't you do that! And tape a subwoofer to each of your ears directly with duct tape, that should rock! [​IMG] [​IMG]

    I dont understand how a .2 LFE would work. The whole point of LFE is to be non-directional, so it wouldnt matter where you put the other sub. If all you wanted was more bass, you can just daisy chain another sub onto your existing one...you woudlnt need an actual second .1 channel to accomplish that.

    And I can understand two front center channels, but what would be the point of two rear center channels, what percentage of DVDs already out would actually accurately have the proper imaging for 4 surround sound channels? I can understand 3, but an additional rear center just sounds excessive.

    Just my .02.

    I read that online as well and thought, "If they somehow manage to make that for home theaters, my wife will kill me trying to hang speakers from the ceiling!" [​IMG]

    Oy 10.2? I guess my HT right now could handle two more speakers, but that's pushing it. 7.1 works ok in my space and I could put small speakers in the other part of the room, but no room for other full-range speakers.

    I'm sorry, but this incessant desire for more and more channels is really starting to get ridiculous.
    No one can deny that 5.1 is better than 2.
    I have a difficult time believing that 6.1 is so unbelievably better than 5.1. (Oooh! A center rear! Wow! [​IMG] )
    Now 7.1 or at least 5.1.1 (the extra .1 for height) is a very intriguing prospect. Yes, adding a height channel will certainly produce a more enveloping environment and create a 3D environment that the current 2D configurations cannot provide.
    But 10.2 is just bizarre.
    Am I missing something or is my practical side simply winning out over my "ooohs and aaahs" side?

    EX (I refuse to call it 6.1) isn't the most earth shattering experience, more a subtle enhancement than anything else. But I'm still glad I've got it. And as for two centre rears, studies have shown that when sounds emanate from directly behind the viewer, the brain can interpret these sounds as coming from the front. (Which is why we are told to put our rears at the sides of the room, rather than the back).
    THX recommend two centre rears set at an angle, rather than a single rear speaker, to combat this odd psycho-acoustic effect. But it's still the same centre signal split into two. And Dolby obviously don't have the same hang-ups as THX, as they're certifying single-rear channel amps left, right, and err...centre. [​IMG]
    And regarding 10.2, hey, I'm just the messenger. In case you're interested, Holman's system consists of five fronts (Left, right, centre, and a mid left and mid right to go between the left and right fronts and the centre), two front height channels (one left, one right) three rears (Rear left and right, plus a single rear centre), plus two subs. Practical? Not for the average HT nut on this forum. But one day, one day...

    I think the point of the ".2" is to have a seperate sub for front and rears
