Thank you! Moving DNS to google 8.8.8.8 fixed the netflix streaming buffering problems immediately! I also took the time to setup the new router on openDNS. I'm on Time Warner Cable SoCal, iOS 5.0 (5.1). Netflix playback would buffer every few minutes, for a minute or two at a time. I have hard wired ethernet on the Apple tv, and PCs on the same router (wired and wireless) stream netflix just fine on my ISP's DNS.
