Ok, here is my question. I have the app on my HTC One (M8) phone. I installed the new Amazon Prime app and, while the app works fine, I cannot seem to get it to cast. So, what is the very best app that will cast ANY streaming video I have on my phone to my TV. By that I mean what 3rd party app puts the little chromecaster box on the video I am watching, or anything else the phone has on its screen?
