Airplay
I am totally lost. I own Apple TV but I do not remember setting up an Airplay account. If I did, I have no idea what the password would be. Now i just want to connect my iTunes library to my iPhone. I don't have any idea how to do that. I can't even use the same library on two different computers in the house. The PC I own has a different library, but I don't especially want that. I wish things were better explained to an old man who has no plan to become a computer whiz.
