That's interesting, thanks.
Tried this? It might be a bit of a pain to go through it just for Eurosport output though.
But that seems to be enabling a match between the Firestick and the TV, whereas what I'm talking about is a mismatch between the Eurosportplayer App and the Firestick?
Or in my case, is the Firestick simply enabling the mismatch between the App and my TV to be displayed, by producing the juddery motion?
