Ps3 + V663
I got both of my units a week ago and am finally getting around to playing with high def audio. I'm disappointed that the receiver will not show "DTS HD-MA" when playing that through the PS3 - it only shows "DTS" when I output Bitstream, and shows "PCM" when I have the PS3 output Linear PCM. I'm happy, though, that the receiver will let you analyze what type of input (3/4/0.1) it has coming in and the PS3's info screen will show that DTS HD-MA is being output.
My first impression of the Yamaha is that it is not nearly as loud as even my old Pioneer VSX-811S. Until I turn it nearly all the way up, though, I shouldn't complain. The 0.5 increments on the volume likely give a better control over the exact volume being played.
The unit also solves my problem of outputting to both my plasma and projector. When playing my 50" 1388x768(ish) plasma, I send the component video signal whereas when I play the Sanyo PLV-Z2000 1080p projector I send it HDMI. I have to manually switch the PS3 from one to the other, but at least I don't have to change any cables each time I do it. Audio can still come through HDMI when the video is coming through the component video cables. My Directv HR20 outputs both HDMI and component video simultaneously so that's not a problem, either. But the XBox360 doesn't do 1080p so I just leave it as outputting 1080i via component and if I'm watching the plasma then it come through as component whereas when I turn on the projector I see it come through as upconverted to HDMI 1080i. So I'm happy with the receiver for how I will use it - a great bargain at $366 shipped from Etronics.
If anyone knows how I can send Bitstream to the receiver and get the "DTS HD-MA" lights to light up, I'd appreciate a post (even though I know I'm listening to uncompressed high def DTS HD-MA when I decode it at the PS3 and send it as LPCM).
