Hi, Looooong time lurker, first time poster! I just bought an Apple TV 3 and upgraded to OS 5.1. Whenever I try to view movies or TV in HD (720p or 1080p) I almost immediately get the message: "An error occurred loading this content. Try again later". If I switch to Standard Definition in the store settings then the content loads without a problem. I tried calling Apple Care and the first guy I spoke with made it sound like there is currently an issue going on with Apple's servers. However, when I spoke to a senior advisor he said it was most likely my WiFi connection. I'm getting WiFi d/l speeds of around 6Mbps. Shouldn't that be more than fast enough to stream 1080p content given a couple minutes of pre-buffer time? 1080p streaming has worked a couple of times but it's very inconsistent and error prone. Has anyone else seen this occur recently or after upgrading to 5.1?
