I bought this adapter with the intention of connecting my ipad to my tv and streaming apps such as Lovefilm, BBC iPlayer and 4od. Be aware that none of these applications will work when connected via HDMI to a display. You will receive a notification that states the app does not support.
Possibly ignorance on my part, but to me, this was a big plus point of buying the adapter in the first place. I contacted 4od and received the below response when I asked why there was no support:
"Unfortunately the reason Airplay no longer works is that we don't have the rights to broadcast all our shows using Airplay, so this feature is not enabled."
