Your browser does not currently recognize any of the video formats available
Don’t worry about it.

The snippets of text you see in search results are what the webpage responded when the webcrawler was indexing it. Most of the time those error messages aren’t relevant to you at all.

In this case it’s not saying your browser isn’t recognized, but rather that the GoogleBot couldn’t play that YouTube video.

In other words, you’re fine. If you can play that video, then that’s all you need to worry about.
