I've been having some strange problems getting my new Apple TV to communicate with iTunes (latest version). I have Parallels build 5160 installed on OS X 10.4.9 Using the Bonjour Browser tool, I've discovered that iTunes uses the Parallels Host-Guest address range for its _appletv-itunes._tcp. - 1 Bonjour service. If I stop that, it uses the Parallels NAT address. As a result, (I think), the Apple TV to iTunes communication breaks down after an initial sync. Is there anything I can do about this?
