Last night Streaming a movie to the ATV I got about 2/3 thru it and it cut out. I found that all my shares were gone, and the ATV was no longer in the Device list. I had to set up a new link to an Itunes library, but it took two or three shutdowns of Itunes on my Mini to get it to see the ATV again so I could enter a new code. I never had this happen pre the last update. Anyone have anything similar happenning since we updated last week?
