The problem is that my Apple TV will no longer connect to the iTunes on my computer. Shared movies will not let me access the content in my iTunes movie or tv shows libraries. This is content I own and have saved in iTunes including my home movies of my family on vacation.
I have restarted my MacPro Tower, tried with my iMac, deleted all the computers and remotes associated/connected to the Apple TV, unplugged everything from the Apple TV, and tried restarting my modem and my router all to no avail. The Apple TV sees my computers but stops there.
My Apple TV remote is sluggish as are the Apple Remote Apps (v 3.0.1) running on my iPhone 3Gs and iPod Touch.
Apple TV will not access the "shared movies" or "shared tv shows" options and seems to be restricted to the content that was saved on the Apple TV hard drive. I have about 10 GB of free space left. Apple TV will not access the iTunes store. I do not think this is strictly related to the iTunes store or a server issue because I cannot access my computers with the Apple TV, and to my recollection there has not been an iTunes update this week. App Store does not list an iTunes update in the last 30 days and the Apple TV has not been updated in many years.
I am running OS X 10.9.2, iTunes 11.1.5 and my Apple TV is running 3.0.2.
One odd thing I noticed is that something called "IR 3.1.2" showed up briefly in the "About" menu of my Apple TV in the area that usually reads Software Version. When I backed out to the main menu and went back to the About menu, the IR 3.1.2 was replaced by Software Version 3.0.2.
