Here is a new source of an Amazon employee saying that the App is coming:
I would like to inform you Amazon video business team is currently working on providing service on NVIDIA SHIELD. We have been receiving numerous feedback up on this issue, and we have taken this issue as a top priority.
[...]
As our team is working constantly to provide Amazon video service on NVIDIA SHIELD, I humbly request you to show your kind patience.

Here is a Nvidia employee indirectly saying it's coming (translated from german):
To make it short, 2 people complain that Amazon Video is still not available on Shield even though it is working on Android TV already (Sony).
The employee answers that "they are continuously working on bringing the best and most famous Apps to Shield TV".
Then someone else says (paraphrased): "doesn't Amazon prevent a release?"
Employee then answers "A little more patience :)".

So i sold my nexus player to a friend 2 weeks ago because i got tired of waiting for a solid way to watch live tv on androidTV
Well i was too impatient because upon tweaking my new windows kodi box, i stumbled on this little gem in the forums, someone is developing a TVHeadend Live channels app

So I just found this old thread of someone asking whether a One for All Remote supports the Nvidia Shield TV which never got answered.
https://www.reddit.com/r/AndroidTV/comments/3nlymv/anyone_got_any_experience_with_the_one_for_all/
I own the One for All 7980 Smart Control Universal Remote (which is configurable via an App and Bluetooth) and it works with the built in IR Receiver of the Shield.
The code your looking for is "4918".
What works:
Although it seems like an Android TV IR limitation, the following buttons do not work via IR:
The only thing I'd like to see in an upcoming update is previous/next because it would be useful for Spotify and Plex. As the Logitech Harmony remotes also don't support this it seems like Nvidia needs to add this functionality themselves.
Other than that the remote works just fine. I even sold the included controller because I don't play any games on Shield.
Hope this helped!
