I don’t know if this has anything to do with the aTVFlash or not, but my AppleTV has never had any syncing options in iTunes. When I select AppleTV in the iTunes Device list, I only see two tabs (Summary & Photos) and my account is an administrative one. Interestingly, the aTVFlashed AppleTV I bought for my parents does display correctly in my mother’s admin account, but my father’s admin account looks like mine. They are using an Intel iMac and I am using a Mac Pro. We are both running the latest Leopard and iTunes.
Any ideas on this one? I’d like to be able to sync some of my file to the AppleTV’s HD.
