Here are some tips of how to stream movies from PC/Mac to Xbox One via Plex media server.


  • Any Windows PC, Mac OS X computer with a folder that contains media files
  • Xbox One gaming console with Media Player app installed – if you haven't done so yet, download and install available Xbox One updates and be sure the Xbox One has Media Player app installed, this is necessary to play the video and/or audio – if the Xbox One doesn't have Media Player app yet you can find and download it quickly from the apps section of the console, it's about 45mb
  • A TV connected to the Xbox One
  • Go to Plex.tv and download Plex Media Server here onto the computer and install it, it's free, you do not need to sign up for anything if you don't want to
  • The PC or Mac and Xbox One must be on the same local network (wi-fi or ethernet)
  • Assuming you have met the fairly basic requirements, you're ready to configure and setup streaming from Plex Media Server to the Xbox One and the TV.

Now that you have the Plex app on a computer and the Xbox One up and running, the rest is really easy:

1. Launch Plex Media Server on the computer, this will open a new web browser window where you can configure the media server

2. In Plex app, choose "Add Library"

3. Still in Plex, now choose "Add Folders", navigating to the directory on the PC (or Mac) where the media you want to stream is stored (you can add multiple folders if you want to, including your iTunes Library from ~/Music/)

4. Now from the Xbox One start screen, go to "My Apps and Games" and find and open "Media Player" from the apps menu (if you haven't done so yet, you can download it quickly as shown below)

5. Wait a moment or two and Media Player will discover the Plex Media Server app running on the computer and the video / audio library will show up on Xbox One, it's easily identified and will show the name of the computer running the server.

6. Use the Xbox One controller to navigate the media library in Plex

7. Select and play videos which will stream from the computer by hitting the A button on the Xbox One controller. The selected video will start playing immediately on the Xbox One and TV, while the Plex Media Server runs in the background on the computer.

You can play, pause, stop, fast forward, rewind, and scrub any movie or audio file that is streaming, the whole experience is easy and relatively seamless. You'll obviously need to have Plex Media Server open on the computer to have this work, as Media Player on Xbox One will not be able to find media content on the PC or Mac without it.

Another particularly great aspect of using this setup is that if a friend or coworker has a movie, video, photo, or music on their computer that they want to play on the same TV and Xbox One, all they need to do is download and run Plex Media Server to make their media content accessible for streaming too.
