I cant stream HD video using Airplay

Hi! Yes, I have forced quitting the app but not reinstalling it. And yes, the app is the latest version available.

I see the Airplay button, I press it and a big exclamation triangle shows up on my screen. I have no idea about what is going on.

Some months ago, the same thing happened. At that time, I had to unplug the ATV from the AC Power outlet, wait some seconds and then plug it again. This solved the problem (and I still don´t know why, because other videos were streaming correctly).

I´ll try reinstalling it latter when I am at home (I am at work right now). I´ll let you know what happened.

Thanks!!

Updating:

Well, I tried removing and reinstalling the app. Nothing happened. 😟

But yesterday i realized something: the Globo.tv is an app that provides some unprotected videos and lots of protected. To wach it you must have an account with them. Well, I do. And used to wach all videos with no problems. Well, I realized that at some "point" I now can only Air Play "opened" videos. All others protected with login process, does not work. 😟

How login works: I need to login at the app once. Then I can wach any video I want.

Any idea what is going on?

Another info: I can start waching the video and then click Air Play. It won´t work. If i do the same with an unprotected video, it works fine. 🙂

Thanks!
