I'm at my limit with the appleTV. Youte works fine on my iphone and ipad, but on my ATV, youtube has to stop and buffer, very slowly, with each stream. Oddly, everything works fine on hulu. I have reset everything, connected it to the router with an ethernet cable, tested the connection (30 down, 1 up) and nothing! What is wrong? Some days I will see the buffer bar fly across the bottom of the screen. Most days, it does this.
