(apologies for the cross-post, but I'm not sure where the problem lies.)
I recently purchased a Sony VAIO VGX-TP1 home theater PC. This computer has an HDMI output so I connected it to the DBS IN port on my receiver (a JVC RX-D411S). This is the same port, with the same configuration, that I used with my HDMI cable box without incident.
My television displays "No Signal" when DBS is selected on the receiver and the computer is turned on. The HDMI light on the receiver does not illuminate when the computer is on. If I connect the computer directly to the TV's HDMI input, I can see the computer output clearly on the TV.
When I change to other settings, such as VCR (my PlayStation 2) and DVR/DVD (my Xbox 360), the HDMI light illuminates and both sound and video come through without a problem.
What would cause the receiver not to recognize the HDMI connection to the computer?
