I still think you didn't understand my post...
HDMI CEC does not have a real standard, every brand is just implementing a variant of this with its own propriety code, just from commercial point to "bind" you with their own equipment. So rather impossible for mede8er to implement something like this.....
As long as those specific HDMI CEC are propriety (not open to the outside world) it is impossible to implement a feature like this. If the brands don't tell what the correct command are, then you cannot program it....
As long the big brands like Sony, Philips, etc, don't agree on a standard (and why should they, they will just say buy equipment of our brand if you want this feature to work) it is just impossible.
Better to look for a remote control that can do the job of switching devices automatically, such as a Logitech Harmony.
That is a feasible solution for this, and I know a lot of us are using such a remote (I also do).
It works like a charm and you can get rid of all other remotes, just put them in a drawer...)
