I upgraded my HTPC yesterday to the new 10.6.8. Getting ready for Lion later this year. Anyway I have had no issues with home sharing for a very long time. Ever since I upgraded, my ATV's do not stay sync'd. Even while watching a movie if I pause it to go take a break, the ATV stops recognizing ITunes. I need to come to my HTPC, stop Itunes and restart it. At this point the ATV will see the library again. Until the next sleep period on my PC (Mac Book Pro). My ATV is set to never sleep. Has anyone else experienced this issue? How did you resolve it or should we just wait for a new iTunes?
