Reddit User’s Commen Question:
“ I’ve read that officially Roku supports mkv but I believe that goes as far as the container but not necessarily other codecs. My issue is I have a fair amount of mkv’s that will play, but they constantly stutter and skip as if they are in slow motion. I suspect it’s the audio codec used and not necessarily the container/video codec. Is there a windows tool I could use to change the container to mp4 or (and I said what I suspect is the real issue) re-encode the audio to some other format? My goal being that I don’t want to re-encode the video and don’t believe it’s necessary.” – Source >> here.
