    Hi Everyone

    Please could somebody explain DD Ex. I have a 5.1 KEF 2005.2 setup with a Yamaha 640 Amp.

    I thought Dolby Digital Ex and DTS es was only for 6.1 setups? Without the extra rear speaker is DD and DTS the only sounds formats I should play?

    I ask this because my Terminator 2 DVD plays the DTS 5.1 sound track as 6.1 Matrix es.

    If anyone has the time to answer these muddled questions.

    Thanks

    Dolby Digital EX is for 6.1 but will play on 5.1 systems. The data for rear centre will be in the data stream of the Left Rear & Right Rear channels. This will be decoded with EX decoder to rear centre but if you only had a Dolby 5.1 decoder the data would be played back thru the rear Left & Right (the data would not be lost).

    DTS-ES (matrix) will do similar as Dolby EX

    DTS-ES (discrete) actually has seperate data for that rear centre channel as opposed to matrixed in the Rear Left & Right channels as it is with Dolby EX & DTS-ES matrix versions.

    DTS-Neo 6 (music or movies) will take a stereo source & decode it to the 6 channels

    Dolby Pro Logic II (music or movies) will take a stereo source & decode to the 5 channels

    There are more formats still if you are interested.

    Thats great, thanks for the info.

    Just got really confused as the Terminator 2 DVD has a DTS ES 5.1 soundtrack but will only play in 6.1 on my decoder.
