CEC sucks. It doesn't have nearly enough standards of definition to allow it to work anywhere near properly.
The best solution, as it ALWAYS has been, is to use a good universal remote.
A universal remote will actually work to start up and shut down equipment once it is properly programmed. In fairness, some manufacturers have gone to very proprietary control schemes to ensure nothing in the world will allow them to be controlled effectively. That's what we get for buying cheap stuff I suppose.
