I am currently having issues with rebuffering when streaming video. My iTunes library is way to large to put on the ATV so streaming is my only option. I am trying to determine the best way to connect so lag is as minimal as possible. I am thinking of buying another Airport Extreme, connecting the external HDD to the Airport via USB, and connecting the ATV to the Airport via Ethernet. I figure this should eliminate the most lag through the network since everything will be wired. If someone has a better suggestion I am open to ideas. I don't want to spend a ton of money to get it working, but other than that I have no specific criteria. Thanks in advance.
