I've just connected my GTV to my receiver. I have my blu ray player and my PS3 connected to the tv via HDMI. When I try to playback a movie in either the receiver won't recognize the digital tracks. I have audio but the red light won't come on and say Digital. However when I play digital files with AC3 tracks it lights up just fine and says Digital. I saw another thread that suggested GTV Settings > Picture & sound > Optical audio output > PCM or Dolby. I don't have those options though. When I go to GTV Settings > Picture & sound > there are only Sound adjustments greyed out, MTS audio, Alternate audio, Speakers, Sound effects, Notification sounds, and Text-to-speech. I've already chosen Audio system under Speakers, but it hasn't changed anything. Does anyone know how to get it to read the digital audio through the optical out?
