IE 11 and 4k playback
I have noticed, that on IE 11, i cannot playback the 1440p or 2160p videos. I can change qualities up to 1080p which work fine, but beyond that I get "Error loading media: File could not be played". I have no issue with Chrome or Firefox.

Any idea why this is happening? I can play 4k videos from Youtube in IE without a problem.
