Sometime ago I acquired a Panasonic DVD-A7 DVD/DVD-A player. I haven't yet bought my first DVD-A disk, but wondered what would happen if I listened to a regular DVD through the 6-channel analog outputs. I selected a DVD that has both Dolby 5.1 and DTS outputs. My receiver (Outlaw 950) can decode both via coaxial connection.
I was surprized to hear perfect 6 channel output on the analog lines. In fact, I couldn't detect any difference (other than a 2db level change) (the 950 has analog bass management, also) between the Outlaw decoded DTS, and the analog outputs.
I'm still very new to the digital audio world, but why/how is the Player able to extract 5 discreet channels from a regular DVD-Video? I also get approximately as good sound when I select Dolby from the DVD disk-level menu.
Any help would be much appreciated. I haven't found any ideas in the manuals.

You are simply using the DD/DTS decoder in the player.

  Hi, while on this subject, so there are decoders in the players? Unlike the normal CD and DVD players that only have the 5.1 available through a digital output(no internal DA converter)?
  I'm currently using a combo DVD/CD, that has 5.1 anolog out(try to find one of these now!), so if I was to go for DVD-A or SACD, I wouldn't need an outboard processor to go into my anolog reciever, that does not contain a DA converter? Thanks for your time.

    1. There are many players with built-in decoders for DTS/DD and these have 5.1 analog outputs. AFAIK, this is typical.
    2. There are very few DVD-A/SACD players that will output these formats in digital form. The standard, still, is that these formats are output as 5.1 or 6 channel analog and you must use a receiver or pre/pro with 6channel analog inputs.
