Unfortunate my suggestions was unable to resolve your issues. For testing purposes you can also temporarily eliminate your router by connecting your Apple TV direct into your cable modem via ethernet cable. This would also let you know if the issue lies within your router. Good luck

Thanks; I too, need to now be on the same local network.
I too have 3rd Gen Apple TV which worked fine then randomly began having this issue. I do not have any firewall or alike software and normally a simple reboot usually help; in this case failed! I configured DHCP reservations for Apple Ethernet & WiFi connections via my wireless router, manually assigned the addresses in Apple TV Network preferences, restarted the Apple TV device, I'm now able to use home sharing via WiFi but ethernet not ethernet. To troubleshoot the home sharing via ethernet connection, I disabled my IMBP WiFi Card, connected both MBP and Apple TV to my router using ethernet cables then confirmed home sharing worked. Additionally, based on the Apple's TCP/UPD chart and using Terminal, Activity Monitor, and Network Utility I was able to verify daap uses 3689 (iTunes Sharing) and not as 5353 (Bonjour, AirPlay, Home Sharing, Printer Discovery, Back to My Mac) as the chart recommends.
Being on different networks in the past I had no issues or who knows, perhaps overlooked. What caused it? OSX update? iTunes bug? not sure.
Conclusion: Both devices (Apple TV + iPhone, iPad, MacBook) should be on the same netowrk (Wired or Wirelessly) and should work just fine.
