[Q] Any way to force bitrate on (rooted) Fire TV? topic

On my Fire TV amazon streaming never plays in HD for longer than a few seconds. On my ipad, PS3 and PS4 its even worse stuck in perpetual fuzzovision.

Using a PC I can get flawless HD streaming by either adding '?forceBR=5' to the URL or using a user agent faker to make Amazon think i'm using a Kindle device (oddly enough)

I wonder if there is any way to force the bitrate on FireTV, perhaps with an shell command?

really is odd. Thanks in advance :)
