I just purchased a Slingbox 500 specifically to watch TV at a vacation home (and cancel my terrible cable TV service there). I have an AppleTV already installed there, and the Slingbox lists the Apple TV as a compatible device. I assumed this meant I could load an app on my Apple TV just as I can on my iPad and iPhone. It wasn't until I completely installed the SlingBox that I learned the only way to watch on my AppleTV is by using AirPlay. So while technically it works, it isn't ideal. And I am annoyed this was not clear in the promotional material. Looks like I will be returning this.
