IMac receives message "Cannot connect to Apple TV" - Apple TV can see iTunes library and can mirror with iPhone.

Hi all.
I have an iMac (mid 2011) running OS X Yosemite 10.10.2 and an apple TV that my little brother just gave me (I believe it's 3rd gen from serial #).
I can successfully mirror my iPhone 4S with AirPlay, and the Apple TV can see the iTunes lib from my iMac, but when I attempt to connect to the Apple TV from the icon in the tool bar it gives me the message "Could not connect to Apple TV."
Spent some time on the phone with a really super tech, he had me go through the paces with restarting the router, the apple TV, my iMac, checked all the network config etc - no dice.
I even reinstalled OS X.... still no dice.
Has anyone experienced this issue?
The second tech who called me back thought it might be hardware related. I brought this iMac in for a new hard drive less than a year ago after it randomly began throwing kernel panics and finally it just wouldn't boot. I don't do very much with my computer so it's kind of odd that it would have these issues unless there is something fundamentally wrong with the way it was put together. It doesn't take any abuse - not like my macbook!
Thanks in advance.

Had my iMac taken in - RAM replaced & video card replaced. Able to mirror in the store. Restored my iMac with time machine backup and restored apple TV. Still getting the same message. Could it be some network setting I'm overlooking? I tried it while the apple TV was connected via ethernet as well - no dice.
