Hi. I'm not sure if this is the right place for this, but here it goes. I have a 2nd generation Apple TV (4.2.1) that will only play about half of the videos in my iTunes (10.2.1) via airplay. The other half get to the screen where you see the progress bar, it stays at 0.00 and the loading thing constantly rotates. The apple TV isn't frozen, because I can still navigate via the remote. These same files that don't work with Home Sharing to the Apple TV share just fine to my iPad and iPhone 4. Any ideas what is up? Here is the data from inspector in Quicktime of a non working file: Here is the data from inspector in Quicktime of a working file: Any help would be greatly appreciated. Thanks.
