For Apple TV owners that also subscribe to MobileMe, Gallery is an underrated feature. By uploading pictures and video on the go, there’s no need to sync an iPhone or camera with iPhoto at home before enjoying content on a television. MobileMe Gallery and the Apple TV just work, at least most of the time.
After upgrading my broadband service, I had to reset the Apple TV to get it on the network, after which I logged on to MobileMe without issue. After looking at some pictures from a day trip, I tried viewing some video. Instead of a home movie, I saw a dialog box that said, “an error occurred loading this content. Try again later.” I did, many times, always getting the same error. While it’s important to remember that video for the Apple TV must be H.264 or MPEG-4, this was video recorded with an iPhone and uploaded to MobileMe.
At first, I thought the problem might be with MobileMe, but it turned out to be user error, though I think Apple shares a little blame. When adding the MobileMe account to the Apple TV, I inadvertently used my MobileMe e-mail address, not just the user name. Nonetheless, it was accepted, and Gallery photos worked fine, but not video. Removing and re-adding the account with just the user name solved this odd problem, and should work for anyone else experiencing the same curious issue.
