    Not sure if this is the right place for this question but I have noticed some dvds with DD 5.1 EX and DTS ES. Now I always thought EX and ES was 6.1 and if so why mark it as 5.1 EX on the DVD? And, if I have 7.1, would the two extra speakers pick up what would have been the extra rear???

    If you have a 7.1, the rears will be fed the centre rear from DD 5.1 EX and DTS ES at -3dB each. The reason to have 2 rears is so that you can use them with 5.1 by splitting the surround between the corresponding surround and rear pair at -3dB.

    So DD5.1 EX and DTS ES is in fact DD6.1 and DTS 6.1 respectively?

    And would the rears that are fed the centre be output in mono or stereo seeing as there would have only been the one rear centre?

    Dolby Digital 5.1 EX is just a rear matrixed channel where is DTS-ES is an actual true rear centre channel, Forgot to add that there is also a DTS-ES Matrix rear channel the equivalent of Dolbys EX.

    No. It's called DD5.1EX as the centre rear is matrixed on the 5.1 channels. DD does not have any format with a discrete 6th channel.
    DTS-ES consists of 2 distinct versions: DTS-ES Matrix and DTS-ES Discrete 6.1. As the names imply, the first uses a matrixed centre rear (like DD5.1EX), the second has a true discrete sixth channel.
    I already answered this in my previous response (centre rear sent to both speakers at -3dB).
