Connection between Windows PC & Apple TV

Thank you for your thoughtful reply. Regarding Suggestion No. 3 & 4, yes, we have restarted the Apple TV numerous times. The PC is definitely on and iTunes is running and we've turned on Home Sharing.

The guy I'm trying to help is 85 years old. I helped him hook this thing up several months ago, but he won't leave anything alone. I question whether or not he really needed to update his modem & router, but it's done and I can't change it. He writes down passwords and usernames in the oddest places, and he is one that tries to use the same password for multiple accounts. It is extremely frustrating for me to deal with.

And, I don't know what version of iTunes he is running. His iTunes was acting odd yesterday afternoon. After restarting the PC, I opened iTunes, only to see the iTunes screen jump up from the bottom of the page and disappear to my right. We had already restarted the PC a couple of times, and this did not happen then. But, the last time, it did happen. At this point I left. This morning, I talked to him and he said another friend told him how to "grab" the screen and pull it back into view. I don't know how he did it or why it happened in the first place.

He mentioned updating iTunes, but he was afraid to try it, in case he lost his library. Not sure why he thought that might happen.

I'm going to print out your suggestions and take them with me when I go back next week. Thanks again.

You mentioned checking to see that Home Sharing is on. The Apple TV tells us we need to turn Home Sharing on. But, when we check the computer, Home Sharing is selected and on when we check iTunes.

Perplexing.

This is what happens. We are in front of the TV, using the Apple TV remote. The PC is in another room with iTunes running and Home Sharing selected under "Controls".

Using the Apple TV remote, we select "Computers". When we do that, it tells us to turn on Home Sharing, which is already selected on the Computer.

Maybe this is what we're not doing. I'll have to double check on that.

Once again, thanks

Okay, I just got off the phone with him. I had do what you said:

On the Apple TV - Settings -> Computers -> Turn on Home Sharing -> Login with the same Apple ID

After going to Settings/Computers, it said Home Sharing was on. I had him turn it off. Then, had him select Settings/Computers again, and turn ON Home Sharing. He said it asked him if he wanted to use his username or logon or whatever, and he said yes. He said it then changed to Home Sharing On. It did not ask him for an iTunes password, which I thought it should.

Anyway, I told him to get out of settings and go to the "Computer" tab above settings on the Main Menu. He did this and it told him he needed to turn on Home Sharing.

I can't figure out what's going on unless it goes back to his changing out the modem & router.

By the way, thanks for your patience. I can tell you have a lot more than I do.
