Leopard, firewall, ethernet port - ATV appears in iTunes but will not sync
Error message: "The Apple TV is not responding. Check to see that any firewall software running on this computer has been set to allow communication on port 3689."
(Note: I do not see how under Leopard to open or close specific ports directly (without using Terminal or some third party utility) as was possible under Tiger, and as Apple's help articles still blindly suggest.)
Network Utility port scan reads "Open TCP Port: 3689 daap
Port Scan has completed ..."
"daap" ! Yeah, what he said. But I don't know what it means.
The ATV used to sync. No change to network.
I've tried resetting the ATV, turning it off and on, repairing permissions, blah, blah, blah.
The ATV is supposed to be an appliance: you turn it on and it works. (Not even an on-off switch.) Instead it's turning into another techno-project.
