My first guess would be that you have video transcoding disabled. You tested on other devices and it works fine, so I would think it's not the server or the video file. If you have video transcoding disabled for the user, then your samsung TV is trying to direct play it, but maybe doesn't support the codec/container. (might be the mkv container, or video codec, or even the audio codec).
I would try enabling video transcoding for that user and see if that helps.
