Sorry, that's not right either. The "all channel" setting just repeats the same info from another channel (making a 2-channel stereo signal come out of all your speakers, for example). It doesn't matrix surround. In order to matrix 5.1 into 7.1 you need to use something like DPLIIx. With "all channel," I'm pretty sure you're just getting stereo through all of your speakers instead of just two.
Someone else may be able to verify this, but I am pretty certain that if you want full 7.1 matrixed by your receiver from a 5.1 signal, you have to change your PS3's sound settings to 5.1. If you leave it with the 7.1 selections, I don't think you can still matrix a 5.1 signal. The PS3's kinda screwy that way. It's not the fault of your receiver, but of how the PS3 sends multichannel audio.
As I said earlier (and this only applies to multichannel PCM over HDMI), I'm pretty sure the PS3 always
sends the maximum number of channels you send via multichannel PCM. If you have 7.1 selected in the PS3's sound settings, but you're playing a 5.1 encoded movie or game, the PS3 will send 2 blank channels.
If you've playing a 2-channel game (like a PS1/2 game), it'll send 4 blank channels. And so on.
This isn't a problem with bitstreaming since the PS3 just passes the raw audio data to your receiver for processing. But since the PS3 can't/won't bitstream the HD codecs, this is how you have to do it.
EDIT: I vaguely remember some buzz about FW 2.4 fixing this problem. Anyone?
