I received a PS3 for Christmas and installed it in the theater. It is connected directly to the projector with the HDMI cable and connected to the receiver with the optical. The receiver is 5.1 and does not have HDMI. When a DVD is playing everything works well - great picture and 5.1 surround. However when a bluray is played, the sound is only 2 channel. The PS3 is updated with the latest software. I played around in the sound settings menu, but no luck. Is there a setting I am missing? Also I put in the Harry Potter DVD and all the menus worked well. When 2001 Space Odyssey was put in, the opening Warner Brothers screen displayed, but when it was finished, the disc menu did not show (blank screen) even though the sound worked. I had to press the menu button ad then only the options showed and not the background scene. Is this normal?
