Hi Jernej Drev,

By default most modern browsers will try to download the video files unless the video file interacts with the inbuilt video player.

However are you the only one experiencing this and have you tried other browsers to see if this is an isolated issue.

since your windows media player reports that the file is not possible, then this could be related to the video file Codec.

Also check what version is your Internet Explorer, as IE requires H.264 or MPEG-4 codec, you can use this website to check if your browsers is supported [Can I Use|https://caniuse.com/#feat=video]. I tried an MP4 video on IE 11 and it plays the video fine and this is my WMP version.

You might want to read this article from [Microsoft on video playback| https://support.microsoft.com/en-ie/help/2532294/videos-won-t-play-in-internet-explorer]

below is my autoplay feature settings, check yours as well.

However, there are some tools that allow users to play some video format directly an example would be [VLC Player |http://www.videolan.org/index.html]
that you can look into.

Please let me know if this helps.

Regards,
Prince

I am getting the exact same in Google Chrome on Win10, issue surely isn't not modern browser. All other videos / sites work fine.
