Mac unable to by viewed from aTV

hey, after the Beta5 update, i’ve been unable to view my mac via my aTV from the itunes option. i can airplay from my mac to the aTV (its works fine) but my aTV iTunes can’t been seen when i try to view photos or music. I;ve tried a iMac and a macbook, both have the same apple account ID and the same on the aTV. But i’ve been able to use Media player just fine and i know i have iTunes open and is on the same wifi network. I’ve updated to the lastest verion RC1 and still have the same problem. Everything else works perfectly fine other then that option. I was wondering if anyone else ran into this problem ? or if i just updated to 4.4 (updated via mirco usb + seasonpass) and that might fix the problem.
