I have a Sony TV, last of the big tube models but with HDTV. I have one input for HDMI and my satellite tv goes in there. How do I connect the ATV (mod4). I have plenty of analog open plugs. I have found an HDMI switch that seems to feed two TV's. It has one Input and two Outputs... I thought HDMI was bidirectional...could I connect my Sat TV and the ATV to the two "outputs" and connect the Input to my TV. Thanks in advance.
