If you haven't already seen it, the Scurvy.Media source code contains a sample project. It's not very complex, just a simple example of how to use the API to display a short video using the SpriteBatch.

Since you can download the whole repository from the link above, I didn't bother to make a source code release. But if you download the latest commit, you'll see the VideoSample project.
Enjoy! :-)
