    Sorry to all out there but im only a begginer at this.
    I have a sony DAV 800 home cinema system and Sky+, I have connected the two together with an optical cable but the sound only comes from the front, centre and sub woofer, and no sound effects from the rear speakers. Am I missing something.

    You will normally only get sound from the rear speakers if you are listening to a Dolby Surround source. Do you have the movie channels ? Also, make sure your Sky box is set to output stereo.

    I have tried watching a recorded movie that indicates it is DD and have set the skybox output to stereo but still no joy. Could it be the recorded movie does not record in DD.

    If you have set the Sky+ output to Stereo, you will not get DD. You can set the SKY+ to output Dolby.

    Let's get this clear - do you want Dolby Pro logic output or Dolby Digital ?

    Movies do record in 5.1 sound. You need to have the 5.1 sound turned on in the sound option, this is separate to stereo, next one down if memory serves me right.

    In the sound setup menu there is an audio output option which can be set to either mono or stereo. Or there is an optical output option which can be set to dolby d or normal.
    What settings do i need to change to get 5.1.

    You need your sky+ sound output set to dd. The dolby decoder can then detect the format being presented to it. The DD bitstream also contains the prologic encoding(its part of the dolby standard). My Tosihe TV has a dd decoder and correctly identifies the stream from the program source. ONLY movies are dd encoded . ignore what the epg says for sky movies its upto the usual SKY standard (CR*P). DD and DS badged films will either be 5.1 or 2.0 some are only prologic ! (if you look at the dvd boxes not all dd encoded films are 5.1 some are only 2.0 so that probably explains it). Other channels will present a dolby prologic source for you if the original program has dolby encoding in the same way that terrestial NICAM contains the dolby signal for prologic decoders.
