I am going nuts trying to figure out how to fix this. When I use my Apple TV for Netflix, Youtube, NHL, etc it all works just fine. When I try to rent a movie from Apple (iTunes) it has a black screen, the message "Could Not Sign In" and an okay button and that is it.
I have full connection to my WiFi according to the my network info in the General tab. The only answers I have found is to use a micro-HDMI cable but this appleTV doesn't have that. It only has an Ethernet, Optical, and HDMI ports. I have not tried to hard wire it as the TV is on the other side of the house from the router and that is how I want to use it.
Anyone have any ideas before I try to use this as a skipping stone across my pond?
