On every computer I've ever tried to use Unity, the Asset Store seems incapable of showing the YouTube video previews of assets. It always claims my "browser" does not currently recognize any of the video formats available and recommends I click for a visit to a FAQ about HTML5 video. I would expect this to be built into Unity, yet it seems not to be. I can't find anything online about what the deal is. So how do I get the videos to work within the Asset Store within Unity??
