Hi all, I purchased an Apple TV recently and am now trying to get it up and running. Thus far, I am able to stream music and videos from my iMac to my TV. For some reason, however, when I go to shared photos, the Apple TV says it cannot find any. However, in iTunes on the iMac, I've selected my entire iPhoto library to share, and sharing is also enabled in iPhoto itself. Am I missing something obvious? I appreciate the help.
