I have set up Home Sharing on my Ipad and Iphone 3gs and turned on Home Sharing on my new Apple TV. When I click on Computers on the Apple TV I get the message "Turn on Home Sharing In iTunes" but dont get either of my devices. Help!

Make sure iOS is updated on all devices, and software is up-to-date on apple tv. Make sure all devices are signed into same apple id, and that home sharing is turned on. Sometimes rebooting all the devices, apple tv and even the router will fix this. Also, make sure they are all on the same wifi network.
