For the past few days anytime i watch any HD content the picture after a few seconds goes right to standard quality. thought maybe a problem with HDMI cable but i switched cables and no change. I am wireless but i have a good connection and have never had a problem in the past 7 months since buying the Apple tv 2. I also thought since i mostly only use netflix for HD streams it was a problem with them but then i tried the NHL and MLB and the trailers and the same thing happens. Is there anyone else with this problem
