DSM 4.3 added a feature to stream compatible content directly from the NAS to an AppleTV. It worked for about a day before the icon disappeared. Now, it appears sporadically, but everything else works just fine. I'm wondering if this is a Bonjour issue. My iOS devices seldom sync over wi-fi. I tried using NFS manager recently and it complained about the lack of a DNS server on the network. So I wonder if this is all caused by discovery issues. Synology is no help. They claim the feature does not exist, even though they marketed the hell out of it and I have used it successfully before. Should I set up a DNS server or is that irrelevant?
