In particular, during early versions of iOS 5, there were problems with HboGo not working in the mirror mode. The rationale was that that app (or Apple TV) was blocking it specifically since it was defined as a mobile app and they didn't want that functionality (select any episode of any series ever shown on HBO) available on a TV. I just wondered if that was really true or it just wasn't working because it was an early version of iOS 5.
