Jittery/stuttery video

i have no idea, but for some reason i often end up playing a movie or cartoon etc and there is a jittery playback where it stops every few seconds for a moment

i upgraded my server to this stupid spec "this is purely for storing files and jelly fin"  would resolve the issue

but nadda, i have changed so many settings, can someone advise a litle
