So, I used Handbrake to copy severals movies at the Apple TV setting. When I tried to sync the movies to my Apple TV, I lost my network connection (bars disappeared and wasn't connected to the Internet.) I rebooted the computer and the network was back on. I tried again and the same thing happened. I noticed that the same movie was syncing both times, so I unchecked it from the sync list and then the sync went fine. Anyone else have a similar situation?
