    Isn't the new THX Ultra 2 "7.1"? I know that there isn't anything yet that is encoded with 7.1 in mind, but there are processors to create it right??

    Nope.
    People get confused because receiver manufactorer's claim things like 7.1 when they mean their receivers have seven channels of amplification and a pre-out for the subwoofer.
    There is no 7.1 audio format.
    DTS:ES Discrete is the ONLY true 6.1 format.
    DTS:ES Matrix and DD EX (or THX EX if you prefer) are both technically 5.1 formats with extra information matrixed into the surrounds to generate a pseudo "6th" channel. Saying these formats are "6.1" is like claiming that Dobly Prologic was 4.0. It wasn't. It was two channels of audio matrixed into 4 channels.
    Now for sound reproduction in a large room it is recommended by THX (and others) to use two speakers (amplified seperately) to reproduce the "rear center" channel of audio. So yes there are seven speakers and yes there are seven channels of amplification involved. But there are never any more than 6 channels of audio information.

    Excellent description Alan of this commonly misunderstood concept. It is the manufacturers that have misled the average consumer into believing that there is a "7.1" format.

    As a further expansion to Alan's comments, any 5.1 encoded disc operated thru a matrixing decoder such as Logic 7 or similar decoder will produce a pair of additional side/rear channels of information. This is useful for filling a large space with equal energy but nothing more. In an average sized room (2500 cuft or less) you will never need anything more than a 5.1 or 6.1 format.
