Good Afternoon- ATV newb here - obvious by the title Just got my 40 gb ATV hooked up. I successfully completed the first sync with my iMac iTunes library (Auto sync - all music, tv shows, movies, podcasts, and a few albums from iPhoto). I then went into ATV Settings to set up Sharing (my media library is right around 31 gb) in case I ran out of room on the ATV. I went into Settings, Computers, Sharing to set up the link to stream iTunes to the ATV. I received the code, went back to my iMac and opened iTunes. When I selected the ATV as the device, I didn't see anywhere to enter the code provided by the ATV to set up streaming. Am I missing something? I couldn't find anything in iTunes preferences (other than turning on sharing on my network). Where do I enter the passcode for streaming iTunes to my ATV? If all of my media is on both iMac and ATV, is streaming/sharing disabled? Any help would be greatly appreciated!
