So, recently I purchased the pro version of Infuse for TVOS.
So far I've been using it to play videos directly from my Apple Time Capsule.
Every video played just fine, until today, when I tried playing a (The) Grand Tour episode (1080p, 5.1 channels, MKV HEVC H.265, 1.6GB, 71 mins).
The video was stuttering to the point of being completely unwatchable. Even though the very same video plays completely fine in VLC for TVOS or in any other device I've tried so far (VLC in Windows, File Explorer on Android or PlayerXtreme on iOS)
Any other MKV video in H.264 (not H.265) also plays without any problem in Infuse.
Any idea how to make the video play on my Apple TV using the Infuse app?
