Are there multiple "models" ? I see one on sale at Amazon/Target for $149
and then Best Buy with $179. Tried looking at both but none really gives a
"model number".

So what I don't get is - if we have a UHD 4K TV that has say
Prime/Netflix/Hulu app on it - why do we need to go via a FE? Can't we get
the "best" pic out directly off the TV apps? And if so, our only "need"
should be to get the best picture when playing off our Myth, correct? I see
a lot of answers here and other posts referring to Amazon Prime 4K content
- and I am just trying to see what I may be doing or thinking conceptually
wrong in my design.

My foremost need is to allow my FE to play H.265, hopefully play any UHD
content I may have, and to have the ability to pass whatever audio it may
have without compressing it.

It seems that VDPAU won't play 4K but VAAPI and/or VAAPI 2 would at 30 fps?
Is that possible with Firestick/Shield?
