    Could anybody answer these questions regarding the Denon3802 for me please.
    I can't find the answers in the manual.

    What is the point of the "dts" and "pcm" input buttons when it does it automatically if left on "auto"?

    What is PCM?

    Should the receiver automatically jump to Dolby D if a film is a DD5.1 film on Sky+.
    I havn't found a film that does this yet. Sky don't seem to indicate which ones (if any)are in DD5.1

    As nearly all films (DVDs) are in DD5.1 does having surround and surroundback speakers make much differance? Are they (surr back) neccesarry?

    There are a few references to a surround mode "6.1". Is this short for Dolby Digital 6.1 or EX or whatever its called or is it something else?

    Thanks in advance for any help,

    Ash

    1. The point is if 'auto' mode doesn't work you can select it manually. Leave it to 'auto' though.

    2. PCM = Pulse Code Modulation, used for CD-Audio via digital connection (coax or optical)

    3. If in 'auto' mode, yes.

    4. They are not necessary. There are a few DVDs though which support the surround back speakers, those contain either Dolby Digital Ex, DTS Es or DTS Es Discrete soundtracks, see also below.

    5. Correct, DD Ex, DTS Es or DTS Es Discrete are referred to as 6.1 systems, when using two surround back speakers they are also sometimes called 7.1 (also used for THX Surround Ex).
    Actually DTS Es Discrete is the only true 6.1 system and there is nothing like a 7.1 system (yet), so technically speaking the terms are usually wrongly used.

    I have a Denon 2802 amp, and that automatically switches to DTS when it detects a DTS signal from my DVD player. My only suggestions can be:

    1. Your DTS films might be old so thay don't have the DTS flag. Therefore you'll have to switch to DTS manually on your amp. I heard this was the case with some DVD's. Newer films with the flag will make your amp switch to DTS automatically.

    2. Some DVD players have DTS disabled by default, so you'll have to enable it on the setup menu. My Pioneer 444 player is like that. Once you've enabled it, you don't need to keep on enabling it on the player each time you want DTS. The option to have it disabled is for the benefit of customers with older amps which don't have DTS decoders, and it's to protect from speaker damage from the noise produced when you try to send a DTS stream into a Dolby Digital decoder.

    In all cases, make sure the DVD film supports DTS and you have it selected in the disk's Audio menu. Otherwise the disk will play in Dolby Digital by default.

    my 3802 switches quite happily between DD & DTS as I flick the audio track on T2 between the two formats (comparing the bass on the Nuke detonation dream sequence).
