Hi folks, I have my new Pioneer VSX1018 AVR hooked up to my Sony BDP350 blu-ray player. When I play a normal DVD, the AVR auto-recognises the format of the soundtrack and it displays on the AVR's display, e.g. "DTS", "Dolby Digital", etc. However, for all the Blu-ray discs I try, I only ever see "PCM" displayed. Even when I enter the movie's settings and change it to "True-HD", PCM is still on the display. So I'm not entirely sure if my Amp is decoding the soundtrack correctly.... or not. I kind-of expected the amp to display "True-HD" in this scenario. What does "PCM" mean? I'm pretty confident nothing is wrong, so I'm more curious than anything if I have everything connected correctly (I have the Blu-ray hooked up via hdmi).
