Thanks to all who responded to my question. This answer appears to be accurate as far as I can now tell. Thanks. When I switch the PS3 to *bitstream* for watching a blu ray and select TrueHD from the disc menu, the receiver display just reads DDolby and not TrueHD or Dolby TrueHD (as I assume it should?). If I then click *display* on the PS3 remote, it says in the upper right hand corner of the screen, *Dolby* and nothing more. However, when change the PS3 settings back to LPCM (what does this mean, anyway?), the Pioneer once again states PCM, but pressing display on the PS3 remote shows on screen *Dolby True HD* and there is a noticeable improvement in sound. It does the same on discs with Master HD. When I switched to bitstream, the Pio stated it was only decoding in DTS Es, not an HD track. But when I switched back to PCM settings, my tv display states *DTS Master HD* or something to that effect. So, I guess while watching blu rays, I'll be forced to set it to LPCM. This may not be a big deal to some, but I'm super, super, SUPER anal about these sorts of things and looking down at the receiver display during a movie and seeing it state *PCM* drives me bat **** crazy!
