Advertisements The biggest downside to CEC is the lack of configuration. This is in the implementation, though, so TiVo could provide settings. And we both know that the meaning of "on" to a DVR isn't the same as other devices. My 2008 TV supports changing to one input via CEC, I suspect yours does to, but something is leading you to believe otherwise. I haven't played with the Chromecast, but of course CEC isn't the end all be all. I'm just saying I'd rather have the choice to disable it, then not have it at all. Standard CEC does support tuner control, so I believe your one useful use case is possible.
