Oks [GOT IT!!!] for those who have HTC VIVE and have the vive and steam software installed! have the video you are looking at open into like a new tab with only the video, right click the video and hit "save as video" but before you do make sure that the address link has .MP4 at the end remove the .Webm and add MP4 and you should be good to save it as so? After you have it saved to a folder open up "SteamVR Media player [Beta]" and the rest you should be more then capable to do on your own.
