Hi Scott Rozman,
You can take a look at this forum post
where I have explained how to show/play a single video file
There is a control called Image that you can use to show a single image. You can show a simple image using Generic Content control as well.
Thumbnails for videos are not generated if you are running your project in Medium Trust or under Windows Server 2008.
