A few days ago, I purchased a Panasonic BD65 Bluray player. Audio is running via the optical out into a Harmon Kardon Signature 2.0 pre/pro, which only supports DD and DTS 5.1. With discs with a DTS audio track, I'm getting a lot of distortion in the center channel on louder dialog passages. Has anyone else experienced this? I'm afraid I'll have to return the player and go with a different model.
