In order to get the connections right that info is also needed Wink. HDMI lacking on any one component can throw a wrench in how the connections are made.

That said, if I guess correctly on what ports/connections you equipment may have, you could try the following:

Cable box, Blu Ray & PS3 (all HDMI out) -> (HDMI in) A/V Receiver
A/V receiver (HDMI out) -> (HDMI in) HDTV
