Live view freezes after couple of minutes

[heinreyn]

When watching the live channels, at first it goes well. Directly after starting, the image turns a few times black but returns immediately. After a couple of minutes the image freezes and a few moments after that the sound stops as well. It doesn't matter how log I wait till it returns, it never starts again. After restarting the live channel, the same issue occurs after a couple of minutes. Doesn't matter the live show or the channel. I have it on both tv's, one with nvidia shield and one with chromecast with google tv.
