Outline Notes for Accessing Plex Media Server from an Apple TV 3 (no jailbreak)

I want to be able to access a Plex Media Server from my Apple TV 3, but I don't want to jailbreak the Apple TV.  The media files sit on a USB drive connected to my WiFi router (so not on the media server PC).

Here is how - no fancy stuff as I've just included all the links I had to find in order to get this going...:

1. Standard Apple TV 3 with latest firmware (6.*)
2. PC running Ubuntu desktop 12.0.4
3. Install Plex Media Server on the Ubuntu desktop PC

4. Install Plex Connect on the Ubuntu desktop PC

...and run it as a cron a reboot as root

5. Modify the Apple TV 3 settings to access DNS from the Ubuntu PC and not from the standard DNS

6. Access Plex Media Server from the Trailers menu on the Apple TV 3

7. Link the USB drive to a media share on the Ubuntu Dekstop
