I have a WD-65738 with a HDMI/HDCP handshake issue (put "handshake" in to the search for this thread) , but before I call Mits back to tell them I'm still having the issue (on multiple devices) after a couple menu 1-2-3 resets, I wanted to make sure I'm understanding HDMI-CEC correctly. They've given me the standard "If the tech comes out and finds HDMI-CEC was the problem, there's going to be a service charge," etc, etc.
I did briefly have a Pioneer VSX-30 that supported CEC, and it worked, I guess, but it was annoying and I turned it off, anyway. I have a Denon DVD-758 and a 360 as my only two other HDMI devices...I don't think either of them support it, and neither does the TV. In any case, I had this problem both before and after the Pioneer, anyway (I'm back to my old Onkyo...no HDMI switching for now).
As long as the TV says I can't enable HDMI-CEC, there's no way it's causing a problem, right?
