I have a problem getting my ATV working with both my computers at the same time. My setup: iMac with 10.8, iTunes library, home sharing active, LAN Windows 7 laptop, iTunes library, home sharing active, WLAN ATV3, LAN/WLAN Both computers and the ATV are using the same Apple ID, the iTunes libraries only have different names On my ATV i can browse through all files on my iMac, but no files of the laptop are showing up. The ATV asks me from time to time which library to use, but it changes nothing. Only the iMac shared files can be seen and played. The odd thing is, that the library of the laptop is shown as a share in iTunes of the iMac. What am i doing wrong? I want to use both iTunes libraries with my ATV simultaneously. It would be ok, if i have to choose which library to use, based on which computer is online.
