Kodi not seeing MP4’s

I am trying to play my video’s through kodi. I was able to setup my music with no problems. both my music and video’s are in my music and video shared folders on a windows 10 machine. browsed to the music and played no problem mp3’s and flac’s. when i browse to the video folder it sees nothing. i have changed the security settings and added everyone to the folder and still when i browse to that folder through upnp it does not see any files. can some one help me, and no i will not covert over a 100 movies to another format.
