My Apple TV seems to have been syncing for hours. In the meantime, i've added some tv shows to my itunes. When I try to play them on the ATV, they don't show up. Is this because they won't show up until the sync is over? Regarding the sync, I keep taking more and more away from what I want to sync but I don't see the available space changing? It would change during the sync in the past but now it appears to be frozen? Is anyone else seeing this?
