My apple tv works great via wifi. I was trying to help a friend who does not have wifi who got the apple tv2 and tried to connect it via ethernet. Auto setup did not work so we typed in his ip address manually and the atv2 said congrats your online! Well it is still not working. We turned home sharing on in itunes 10.0.1 on his mac and it turned on with his mac then we we entered the same info on his atv2 and it could not log in saying either wrong user name or password. No youtube videos no movie trailers and no connection to his mac so even though it says it's connected to the internet it does nothing but play the screen saver. Any help would be great. I know others are having the same issue but perhaps they are on wifi not ethernet.
