The only special case you have is when you have something's that is DD EX, in which case you have to manually select that listening mode on the 875, and there just aren't that many things with DD EX (I think I've hit one DVD with it).

Having just purchased Iron Man on Blue-Ray (claiming TrueHD 6.1 audio) I was stoked. Connecting my new receiver (1 week old) via Monster HDMI 1.3a/b cable, I was sure that I was going to be blown away.
So...when playing the movie, the Dolby TrueHD indicator did NOT light-up on the receiver (and it's capable of ALL but THX). I checked the audio-out for BD on the PS3 (initially set to linear PCM). The Yahama manual states that bitstream should be set for an audio source sending high-definition audio. So, I changed it. Still nothing. In mutiple emails with Sony customer service, they state that I NEED to use Linear PCM for the HD audio formats via HDMI. The only A/V receivers I've seen that are capable of this are from Sony.
I don't have a huge budget (paid $500+ for this one), but would really like to take advantage of the audio from my PS3. Any suggestions for compatible receivers?

The reason you don't see it on your receiver is because the PS3 is doing the decoding. So in truth you do not really need a receiver that supportes True HD and DTS HD in order to get those tracks w/ a ps3

Since the PS3 cannot bitstream the HD audio formats like TrueHD the PS3 will downgrade the TrueHD to DD 5.1 and send that to your receiver.

BTW, when I try to set the 9.8 to Passthrough, it messes up the picture. I get a pink looking menu on the PS3 where it normally is black. Anyone else have this happen?

Does anyone know enough about the Integra to know how to set it to play best with BluRay titles? Do I need to change the settings depending on the BluRays capabilities? Or should one setting be best for all?

Why can't the PS3 bitstream the HD audio codecs?

I don't know other than giving the bitstream advantage to stand alones motivating a selling point. As we know with the right equipment there isn't any difference between bitstream and pcm and there seems to be some rumbling from insiders saying pcm maybe the way to go instead. We'll have to see.

Wall-E (BD) : LPCM>Bitstream
Kill Bill 1 & 2 (BD) : LPCM>>Bitstream
Gladiator (Special Edition DVD) : Bitstream>>LPCM
Top Gun (Special Edition DVD) : Bitstream>LPCM

According to my tests, BDs with Uncompressed PCM and TrueHD LPCM sounds considerably better and with DVDs Bitstream sounded a lot better.

My setup is as follow
PS3 connected via HDMI to Denon 789 receiver.

Hope this helps those whose are confused about it.

I fought with this for 3 hours last night... stayed up way later than I should have. My HDMI cables are HDMI1.3. My receiver is HDMI1.3 capable.

When "Bitstream" is selected from my PS3 menu, I was only able to see "Dolby Digital" when hitting the "Select" button on my PS3 for audio output (and my receiver wasn't able to detect a Dolby TrueHD, either).
