which would enable you to have multiple inputs and one output.
Just connect that to one of your receiver inputs and your receiver output to the HDTV
Something along these lines:
I am updating my home theater. I have a Sony HDTV and a Panasonic HD projector. My receiver (Onkyo TXSR605) only has 2 HDMI inputs and 1 HDMI output). One of the inputs is connected to my cable box (which is a HD cable box), and the other input is connected to my Bluray player. Obviously, I need a new receiver because I don't have enough inputs (mainly my HDTV).
My question is: Should I buy a reciever with another output (2 outputs) - One for my TV and one for my projector. OR should I buy a receiver with just more inputs (mainly my HDTV).
