Airplay will not load movies from my vudu app on my ipad to my apple tv.

I just received an apple tv as a christmas present and was beyond excited. I have been wanting one for a long time now. The main reason I wanted an apple tv, was so I could stream my movies that are in my vudu app on my ipad, to my television. They are both synced together and are on the same wifi network, however it is not streaming correctly. Everytime I click apple tv under airplay, it acts like it is going to send, but it kicks it off and returns the airplay mode to ipad. I even tried clicking on mirroring and that is not working either. I updated both devices with new software updates. Please help!!!
