I have an old TV, with no HDMI input. I would very much like to get an Apple TV box. However, I cannot connect an Apple TV to my TV as it has no HDMI inputs. However, I have a SKY+ HD box connected to the TV, which does has a HDMI port. Is it possible to use this cable to connect an Apple TV box to the Sky+ HD box HDMI port, and therefore view Apple TV content on my old TV?
