1) Can you control Plex with your Apple Remote when Remote Buddy is not running?
No- Input mode "Standard", always running is checked. I have tried unchecked and checked, neither seems to work w/ remote buddy on or off.
2) Are you using Little Snitch or any other firewall software?
No Little Snitch, no firewall software, no Mac OS X firewall
3) When Plex is running, please enter this line in Terminal.app and hit return:
sudo lsof | grep Plex | grep UDP
