Can anyone help me with a little problem I'm having with syncing playback position between my Apple TV and my iMac? The way I understand it, when I'm watching something on my iMac, and I get say, 10 minutes into a tv show for example, when I go to my Apple TV, it's supposed to start playback from that same position. But mine doesn't do that. Is there some special setting I have to look at for that to happen? I have content synced with the Apple TV and some content that I stream from my iMac and neither will sync the playback position between the two. Thanks in advance for any advice.
