Please, dont bash me for using windows, its just easier for me to do, im willing to get another 4gb stick of ram, but not to waste hours to get linux wotking If I had to guess, its the ram, the os is probably eating most of that, with the video living on the page file and not enough of it being able to be on the memory at once, and the stuttering is caused by the video swaping from the page to the ram. When I try to watch something on my TV off of it, It stutters like once a second. The server has a i3 4130 and a 1x4gb ddr3 1600mhz kit, and is running off of wifi, though thats not the issue, it gets like 100-200 megabit speeds. When I try to watc something, theres micro stutters not seen in the video file.

I have a plex/storage server using a windows file share, the server is running a as stripped version of windows I could get from a fresh install (windows 10 debloater and as much stuff disabled as I could get) Yes, I know, windows, it sucks blah blah, but after i had issues with samba on lubuntu, its much easier.
