JetPack 2.1.1 caused video error

When I updated today to 2.1.1, for some reason it automatically resized all my YouTube videos to an unplayable/viewable level.

I’ve been pulling my hair out all afternoon trying to figure it out, but then I deactivated JetPack, problem fixed.

Any idea what I can do to resolve it besides deactivating the entire plugin?

It’s not just the Crumble theme I’m running…I tried activating another theme on the blog, too, and the same thing kept happening.
