Good idea. I will try HDMI 2 with enhanced off and see what happens. I'm guessing it will be fine cause HDMI 1 works fine. Let you guys know and will be sure to let DirecTV know if that is the case.Does the problem occur on ports 2&3 if you turn off enhanced mode? If yes, then enhanced mode is somehow interfering with the C61K detection routine. Sony has the enhanced mode off by default because of issues with some older hardware.
Also if yes report the problem in this way to DirecTV as that will assist the engineers in troubleshooting the issue. Not that they will troubleshoot but theoretically it will help.
