I'm experiencing stuttery picture when watching DVB-T2 HD Live TV in Live Channels app on my Mi Box S. My tuner is MyGica T230 (Geniatech) and I'm using their FTA Tuner Loader app to provide a source to Live Channels app. Codec used by broadcasters is H.265/HEVC.

Is anyone else experiencing this? Is anyone using another tuner and has this working properly?

HD video (1080p) plays fine in Youtube.
