I have an iMac with an airport extreme router upstairs. In my living room I have my television, my ATV, and an airport express base station plugged into the wall a few feet away from the ATV. I have a ton of movies and music on my upstairs computer. And for the longest time had no problem streaming them with no skips or delays or anything. But recently (coincidentally after I did the recommended upgrade on my Airport firmware) every time I try and stream it skips and it buffers for several minutes after every chapter. I have no other devices that use this network, and the computer itself is plugged into the ethernet cable. Any advice on improving streaming for my movies? With music it doesn't pose an issue and I stream all my music to the AtV with no problem. I know obviously video is a different animal but it's just odd that this just started happening.
