I think you have things a little confused.
DD 2.0 on the DVD software is NOT a requirement.
Most (if not All) DVD players will automatically downconvert DD 5.1, DD 5.0, DD 4.0, and DD 2.0 to a 2 channel L&R stereo format for use with your TV or stereo system.
Again this does not require the studios to provide a DD 2.0 soundtrack on the DVD, you get it automatically every time from the DVD players L&R analog outputs.

it may be a requirement unless of course you want to use the often crummy DVD Dacs to do this down-conversion. Some two channel DAC's like you would find in a hi end stereo system won't decode the 5.1 channel bitsteam but will pass 2.0 quite well.
- Yes, if you select PCM output - bstan 23:01:39 12/26/01 (2)
  You are correct, but you must select PCM instead of bitstream for the DVD player output, then a standard 2-channel DAC will decode the signal on the digital cable.
  In order to decode DD 2.0 you need to be in bitstream mode and then you need a standard 5.1 DD decoder in your processor or receiver to decode the DD bitstream signal coming from the DVD player.

  - Also means DVD needs PCM output - bstan 23:05:23 12/26/01 (0)
    I failed to mention that in order to use PCM output on the DVD player, the DVD software being played needs to have a PCM option.

Most DVD players have menu settings for the speaker arrangement, so you can play a 5.1 via two channels and have it sound good. Also my DVD player has a menu selection to "enhance" the center dialog even if no center speaker is used. I use that when listening to an action movie late at night... Then I can hear what they are saying and not have the explosions, car wrecks, gun battles etc annoy my neighbors.
- Only with DVD players w/DD/DTS decoders? - bstan 10:26:16 12/26/01 (0)
  Does your DVD player have DD and DTS decoding?
  For those DVD players that don't, you can still quickly hook it up and use it in a stereo system.
