AirPlay - How to stream Video on 1st Gen on Latest ATV

Hi all, I’m am new here so please bare with me.

Is there anyway I can stream video over Airplay to my 1st Gen AppleTV with the latest ATV installed (installed 06-17-15).

The only options I get is to stream music to it, is there a hidden unlock that I have to tinker with?

I also have a 3rd Gen Black AppleTV that streams fine.

Many Thanks in advance.
