Please help with Pioneer VSX-1018 & PS3 - HDMI issue

[jdlivestrong]

Let me start by saying that my receiver and PS3 just came from being hooked up (successfully) in another room to my Samsung plasma (720p).

I just purchased a projector and hooked up my PS3 via HDMI to "BD in" on my receiver (Pioneer VSX-1018) and everything sounds great. Then I hook up the receiver to the projector via HDMI (HDMI out) and I still have sound, but as soon as I turn the projector on, my sound goes away and I don't get a picture. My receiver flashes "NOT SUPPORT". When I unplug the HDMI from the projector or turn it off, my sound comes back (but obviously no picture).

I tried swaping out the cables and I get the same result...so I went back to just pluging the PS3 directly to the projector and the picture shows up without any problems. I don't get what is happening...I have everything hooked up exactly the same way I did with my plasma.

Can anyone provide any suggestions?

Thanks in advance!
