I’ve seen something similar on MyTVOnline 3 with certain 50fps sports streams, especially during source switching. It really feels like a frame pacing / stream transition handling issue rather than hardware. Since other apps and even MyTVOnline 1 are smooth, it likely points to a software-side limitation or bug in the newer player pipeline. Unfortunately I don’t know of a setting that fully fixes it but it does seem like something Formuler would need to optimize
