In the setup to my Sony 730p DVD player, there is an option to switch the MPEG signal from PCM or MPEG. I currently have it set on PCM and apparently this is for you are connecting to an audio component without an built-in MPEG decoder. Just wondering what this means basically? Surely the DVD player is the MPEG decoder? What else would be an MPEG decoder that you would connect your DVD player to? Can anyone help? Thanks.
