I just bought a PS3 80GB from the US. Together with it, I bought a couple of BDs. When I tried to play "I am legend" on which I chose as its audio output Dolby Digital TrueHD in the disc' set-up menu, my Yamaha RXV1800, equipped with TrueHD decoder, would only decode in Dolby Digital 5.1. My speaker set is 7.1 and I am using an HDMI 1.3a cable to connect the two.
I tried to make adjustment on the Sound Menu of the PS3. It lets you chose your connection, in this case I chose HDMI obviously, and set it to automatic output. But when the audio output list is displayed, it doesn't include TrueHD. Why is this so when I believe that The PS3 is capable of TrueHD output through HDMI? The logos on the casing itself include TrueHD. What could be wrong with my set-up?
