I bought a new AppleTV (2nd generation) about a month ago and since buying it, I have yet to be able to connect to "Home Sharing" with iTunes on my iMac. No computers show up under the "Computers" tab when on the AppleTV and no devices show up in iTunes on my Mac. Originally, I was connected just through wireless but then I switch to ethernet but that didn't seem to fix anything. I noticed a lot of others are experiencing the same problem but I haven't seen a clear-cut solution.
Also, I eventually installed some third-party software called aTV Flash
which allowed me to connect to my shared folder on my Mac (it also allows me to play different video formats which is why I bought it). So I know that its possible to connect to my computer with the AppleTV—just not with the default "Home Sharing" feature that comes with it.
Does anyone know what would be causing this? I can provide more details about my home network if need be (just be specific as to what you need). I can probably just continue to use the third-party software when using my AppleTV but I just find it weird that one of the main features of the product just flat-out isn't working for me (so I'm not sure if its my network or because the product itself is defective). Thanks in advance!
