Solving playback issues

[Popeye13]

Every other update for this app either fixes or breaks the framerate matching, and even the fixes aren't complete because the live-channels or the live Sport doesn't match framerate!

Case-in-point being the recent Premier League matches, where my Roku Streaming Stick 4K is still on the default (And annoyingly) unchangable 60Hz, while the Premier League matches are 50p, so there is a constant and unwatchable judder, not to mention no HDR either, despite it being listed as such.

Watching films is the same issue - 25p / 24p / 23.976 is packaged into a 60Hz container and it looks appalling from a quality perspective! How can this still be ongoing?

The Amazon app is written by and updated by Amazon. Roku just makes it available through the store. You can check the linked forum for ideas and who to blame:

The Amazon Prime app has always supported FRM until an update last fall disabled it (subsequent updates have yet to re-enable FRM).

Prime's HDR tagging is often inaccurate (for several reasons).

As @andyross suggested Amazon develops and publishes the Prime app (for all platforms, including RokuOS), so you'll need to contact Amazon CS about re-enabling FRM.

(Audio aside:  You should configure Audio mode, Preferred Streaming Format, and Digital output format = Auto since the SS4K+ has no Dolby decoder.  Note that ad insertions often cause audio/video related problems/issues, and you'll need to address this to both Roku CS and Amazon CS directly, and otherwise limit/avoid the issue by paying for ad-free subscription tiers if available)
