I have a PS3 fat and it is to my understanding that it cannot bitstream Dolby TrueHD or DTS MA, that I have to configure it to Linear PCM. So thats what I have done....so when I hit select on my PS3 it displays that it is sending DTS MA 7.1, my question is I only have a 3.1 speaker setup (mains+centre+subwoofer) and since the Denon is not decoding the audio does it at least downmix the 7.1 PCM signal to my 3.1 setup or am I missing sounds?
