The box goes into standby when tv is switched off (no signal from HDMI), is there a means to auto power on the box when HDMI signal is on (tv is switched back on) and also 'HDMI in' to switch on as well. When you reboot, 'HDMI in' does switch on if set to auto on, but not when switched on from standby.
we did have improvements for the system, but it seems there are allot to fix in it. Can't tell you for sure. new firmware is suppose to hit SOON tm
My best results for disabling HDMI-CEC is: Enable HDMI-CEC in the menu options and next disable all the features individually. Disabling HDMI-CEC as a whole makes it do unexpected things like turning my AMP on when powering off the media player. using a blocker is the best, need to buy a few of those it seems. Seen the same with other brands too by the way (Android thing).
