I was finding that my description data under Film and TV were only getting updated if I did a restore on my units. Also it was sometime showing that it did not see the network. The way I have my setup is my mac pro is going through Timecapsule and then streaming to both Apple TV's with no sync set up. It streams o.k. but data description updates are a problem. Is this a software issue or do I need to set up a ethernet connection? Has anyone heard of this?
