I just ordered this system from Amazon (via 6th Ave.). I have a brand new Panny TH50PZ700U and a Scientific America HD/DVR cable box. How many HDMI cables do I need? Right now, since I do not have the audio system yet, I just have one HDMI cable going from the cable box to the plasma. Can video signals run through the Onkyo receiver? It has 2 HDMI inputs and 1 output. If so, can I run an HDMI cable from the output of the cable box to one of the 2 HDMI inputs on the receiver, an HDMI cable from the DVD player to the other input on the receiver, and an HDMI cable from the output on the receiver to an HDMI input on the TV? That would allow me to only use one of the plasma's 2 HDMI inputs. Any comments are greatly appreciated. Thanks.
