Full success. No issues streaming to 2 ATV's. Found out, which I figured, you have to format the drive on the mini. Am currently using a mechanical 2TB drive in an older OWC external drive. Once formatted on the mini, hooked it back up to my pc to transfer around 600 movies. Hooked it back up to the mini. Took me awhile to figure this out. Don't use apple tv app. Will only recognize purchased/downloaded movies. But did use the app to change file location to the external. Other than a few more steps, don't have to use itunes anymore. The apple TV's recognize the mini going through computers on the screen of the apple tv. Have to turn on home sharing on the mini. Now to order a 2TB SSD to replace the mechanical drive.
