Home sharing not connecting iTunes to AppleTV

I've been having trouble connecting my iTunes to my AppleTV for the past couple weeks at least. I can't access any of my downloaded movies or music. I'm not sure if it's something in a recent update or something?

I have iTunes version 11.1.3 (8) and AppleTV version 6.0.2 (6646.81.1) and I'm on running my iTunes on my MacBook OS X 10.8.5.

Here's what I've tried:

• I have restarted iTunes, my MacBook and the AppleTV
• I have reset my Apple TV and set it back up again on my network - all connected to the same network
• I have turned off homesharing a few times on both my devices and turned it back on to see if will 'catch' - so to speak

No luck.

Any suggestions?
