have you tried replugging both ends of the HDMI cables, and if not that, try different HDMI cables.
sounds like the handshake has gotten a little off.
In the future, please start a new topic, yours isn't really related to the original. theirs is remote related, yours is HDMI-CEC related. It only tends to confuse things, as people are now answering 2 different questions in the same place. and have to clarify which one they are answering.
