Ok, I have a fairly new ATV2. My iMac is running SL with the latest iTunes. My ATV2 software is also current. I have home sharing on and can access my iTunes library. I can play music from the library, I can access photos and in the movies, I can "see" all the movies, including the info and artwork. However, when I try to play any move (whether purchased via iTunes store or ripped form my own DVDs), I get that little spinner thing, but it just goes on forever and never actually plays the movie. I can, however, play movies from Netflix. It is only the movies in my iTunes library that WILL NOT play. I should mention that all the movies will play fine in iTunes on my computer, I just can't play them via ATV2 on my television. Anyone have this problem before and if so, what is the solution? Thanks in advance.
