WD TV Remote 'Back' Button and HDMI-CEC Control Question

I can confirm the problem. I am having the same issues using the remote of my Sony KDL-37EX500 or the remote of my Onkyo TX-NR609 (RC-803M).

It’s not possible for me to go “back” or “return”. I can also not get to the main menu with any button.

Another problem is that HDMI-CEC is unable to start the WD TV Live. I can shut it down perfectly using the RC-803M, but it’s not possible to power it on.

Please fix it, thanks in advance!
