Apple TV will not show my computer under Home Sharing
I have a 2nd gen Apple TV with latest software update. It is connected to my iTunes account and to my network via WiFi and has Home Sharing turned on using my apple id.
I have iTunes 11.1.3 (most current ver) with Home Sharing turned on to the same apple account as my Apple TV.
Despite this relatively straightforward set up, my Apple TV fails to show my computer or my iTiunes library under Computers. I have access to all of my purchased movies and shows via the same account, but not Home Sharing.
In the past Home Sharing has worked but at some point something changed after an Apple TV software update and now nothing I do can bring Home Sharing back online.
There doesn't seem to be much that can go wrong here but maybe I'm missing something.
I'm on a brand new iMac with Mavericks (but this began on my old iMac before the upgrade).
Any help is appreciated,
Dave
