This doesn’t seem to happen all the time, but occasionally when I’m watching streaming the untouched m2ts files from the UK boxset of The Sweeney the video starts becoming very choppy and stuttery and sometimes will end up just freezing completely even while the audio still plays. Just restarting playback of the file does not usually fix the issue. Sometimes I have to complete force kill Infuse or even restart my AppleTV to get it to start playing back the files correctly again. I can often watch multiple files in a row and then just out of the blue, the next episode may either start playing choppy from the beginning or it will start acting up somewhere in the middle of the episode.
From one of the m2ts files this is from MediaInfo:
