Likewise Apple TV HD movie downloads with DD - the amp won't switch to display DD - only LCPM

PS3 output set to Linear PCM not bitstream if that matters

Is this a problem or is LPCM the best quality available?

Confused - anyone help?

What are best settings for me?
I'm not familiar with that Sony but as long as it's HDMI 1.1 or up your OK. The PS3 cannot bitstream. It decodes the HD audio and sends it as PCM to your AVR. Linear PCM is the correct settings to have on your PS3. So yes, your AVR should display LPCM while using the PS3. Hit display on your PS3 controller(you can hit triangle then display or select) and this will pull up a screen that tells you exactly what the PS3 is outputting.
