Although I've been running my Home Theatre now for about a year and have never had any problems with the various inputs, I find myself confused all of a sudden. I purchased the new Digital Video Essentials calibration DVD (which is excellent by the way) to finally calibrate my system (long overdue). One of the audio tests did not seem to work as expected or as narrated by the DVD. It was the Speaker Output and Placement test(s). The first part of the test deals with Stereo, and Left and Right Mains and Center channel. First of all it said to put my system in "Stereo Mode". Wasn't sure what that meant because I'm running Digital Optical input from my DVD player (JVC XV-S500) to my Receiver (JVC RX 6010V) No analog input whatsoever. When the test ran from the left speaker to the right the sound was NOT coming from either of those speakers alone but somewhere in the middle for both tests although when the sound indicated it was back in the "Center" it sounded as such. I probably got my DVD and/or Receiver settings wrong for the test. I intend to try it again. I was a little rushed when I brought it home. I read the "Primers" when I first got my system and discovered this site and got everything set up just right. But because of this test confusion I need some clarifications. On my DVD Setup Menu is has... Digital Audio Input PCM Only Dolby Digital/PCM Stream/PCM My understanding has always been... PCM Only - Other Digital Device Dolby Digital/PCM - Dolby Digital Decoder (My receiver) Stream/PCM - DTS (or MPEG) Correct? So what's "Stereo Mode"? I'm assuming I don't need to touch the "Analog Downmix" setting on the DVD player since I'm not using Analog. The Receiver does Dolby ProLogic and PLII. By the way the Audio Tests that come with T2 Ultimate work just fine. Am I missing something? Thanks.
