Help please: Can't sey up mediabox

I've read the directions two times and scanned the Forum. I'm not understanding what I'm doing wrong in setting this up.

Plugin enabled. Module in place. I put this code for a YouTube Video in both an article on the page "test mediabox"http://bournedigital.com/testing-mediabox.

All I get is a popup with 404 component not found.
It could be I'm putting the code in the wrong place, using an article. I tried putting it in the module under plugin code but that didn't work for me either.

Or I could have the syntax of the code wrong.

Or I may be not understanding something.

Help please.
