This is kind of a double post from the newbie forum, so sorry up front but after a little response I figured out it's really a receiver specific problem. The problem is whith my directv. It works perfectly with true DD 5.1 signals and the receiver switches to Dolby dital on it's own. The problem comes when I switch to a non-DD channel, the receiver sets the surround mode to Off leaving just the front 2 speakers active. I would think you'd want non-DD signals being processed with Pro-Logic II so I figure I have something set up wrong. Can anyone shed some light on this little problem? Here's a link to the Manual, which is sorely laking IMO.
