My Stutters came form LAN conneciton issues, after I improved the quality of the LAN they are dramaticly redused. You can test if this is an issue for you by playing the files on the TV server to see how well it plays there. If it plays properly on the tv server you can focus on LAN and client specs. Also the disk of the tv server is a problem, when its recording programs and your watching recordings or live tv it becomes a real problem since the disk gets to busy. Would be nice if that could be improved. Next stutters came from the codec, not real stutters but also not smooth playback, fram skipping etc. MPV works the smoothest for me but with less picture quality. FFD has better picture but just does not play entirely smoothly. The powerdvd codecs are great, but alos not smooth for tv playback somehow, still need to work that out
