I have a iMac with 2 AppleTVs all connected to a D-Link DIR-655. I used to run iTunes on Windows 7 and everything worked fine (before I got the iMac). Here's the problem - since moving over to the Mac, when the AppleTVs are wire connected to the network, the iTunes library on the iMac will not show up in the AppleTVs. The AppleTVs work fine otherwise (they can both connect to the Internet with no problem). I also cannot see the iMac's iTunes library or the AppleTVs in the iPad's remote app. When I then disconnect the ethernet wire from the AppleTVs (so they hook up wirelessly to the DIR-655), it works fine (iTunes library on the AppleTVs, and everything is showing up in the iPad remote application). After the wireless connection is established, if I plug the ethernet wire back into the AppleTVs (to take them off wireless and force them back onto the network wired), it works fine as well, until I reboot the iMac, then back to square one with the same problem.
As mentioned, it works fine with the Windows 7 PC, but if the iMac is turned on on the same network router, same problem with the Windows 7 PC (library will not show up in the AppleTVs). As soon as I turn off the iMac, the Windows 7 iTunes libraries show up in the AppleTVs (no need to wirelessly connect). There's clearly some conflict being created with the iMac with the DIR-655 that's causing this. I've tried enabling Multicasting and port forwarding TCP 3689, and this didn't fix it either.
