I am having this issue as well on my Fire TV Stick, but not really on my Fire TV. On the Fire TV it does it for the first 30 seconds then goes away.
Question I have is how do I un-install the current version of the video player? All I see is a single Tablo app referenced in the app manager. I would assume that is the app itself not the video player?
How do I side load the older version
Sorry for my ignorance, I am only 1 week into this.
