I'm trying to watch movie trailers using FrontRow, but the program states "not connected to the internet, check network settings" although I am connected to the net. Any ideas...
http://support.apple.com/kb/TS1357 might not apply in this case if you're using the computer in your signature. The router/switch you may be using, or also your computer's built in firewall may be blocking the port for some reason. Creating a new network location sometimes fixes the issue.
