PS3 Blu-ray Settings for Yamaha RX-V663?

[Xandure]

I just recently picked up a Yamaha RX-V663 A/V Receiver and I have the following questions...

1) What are the proper settings on the receiver in order for it to automatically switch to DolbyTruHD or DTS HD?

2) What are the proper settings on the PlayStation 3 in order for it to send the correct signal to the receiver?

I have gone through the settings and adjusted the HDMI audio out for Linear PCM and the Optical audio out to Bitstream. I also checked the audio settings and set it to automatic. The list includes all the 2ch frequencies all the 5ch frequencies and the 7ch frequencies.

Now I have the game Uncharted: Drake's Fortune. I was messing with the audio settings and noticed that I could select the Linear 7.1 ch setting. (It sounds AMAZING).

Of course on the front of the receiver it indicates which speakers are activated for the different modes. I would notice that when I was watching a trailer off the HDD it would switch to 2 ch stereo and when I would return to the XMB it would switch back to 7.1.

My one problem is whenever I play a Blu-Ray Movie that supports DolbyTruHD or DTS HD the Logos do not light up on the front of the receiver indicating that it's recieving the signal.

One other thing, I noticed on the list of audio frequencies supported by the receiver included DTS 5.1, but there was no option for a Dolby TruHD or DTS HD.

I'm I missing something or is Sony not telling us something?
