I have a 3rd generation Apple TV and typically have the iCloud account set to mine. However, another member of my family is starting to use iMovie Theater and their videos do not appear on the Apple TV as we have separate iCloud accounts. It seems that the iMovie Theater app on the TV is tied to a single iCloud account.
I know that you can add multiple iTunes accounts to the device, but is it possible to add multiple iCloud accounts? Ultimately, I'm looking to have the iMovie Theater show videos from both of our accounts.
