It then went back to the list of movies and every one said 'unknown' as the title with no artwork or anything. I then restarted iTunes and the Apple Tv. Once they'd restarted, the Apple TV showed no content at all anywhere. On my computer I could see the Apple TV and it showed no content on the HD at all. Even though it was setup to show all content, it clearly wasn't working. The only way I could sort this out was to delete the pairing to my computer and re-add it. Everything now seems to be working again, but my question is whether anyone else has had a similar problem and if anyone has any idea what caused it? what made it worse was all this happened while I was demonstrating how cool the Apple TV is to a sceptical friend!
