I hope someone can assist with this please. When setting the DNS server on my ATV2, do I use the WiFi or Ethernet IP address of my Mac Mini? My ATV2 is connected to my mini via Ethernet and then the mini is connected to the internet via WiFi, so there are two addresses on the mini to choose from.
It’s whatever IP your PMS is running on. An easy way to figure out which IP to use would be to run the PlexConnect.py file and look at which IP address it shows… It will be one of the two that you are suspecting. Or, you can just launch Plexconnect, plug in one of IPs into the aTV DNS settings, and just see if that’s the right one. If it does not connect, try the other one. Process of elimination
