I (currently) use FireTV which has a limited remote in terms of buttons and keys that work with Channels DVR. But I use a Harmony hub and I understand that I can use, say, the shield TV as a generic android device to control my FireTV and the Channels DVR have get access to additional features such as channel down pages down the guide instead of having to go line by line.
So, my question is if there is a master list of commands channels DVR supports and which implementations (e.g. Android vs AppleTV vs Roku, etc) of the apps support which commands?
This would allow me to access as many features as possible when using Channels DVR on my FireTV.
Or maybe show me I should change to another ecosystem (e.g. AppleTV).
