I want to display a video on an external monitor while the computer is locked (so that no one can walk up and stop the video, access my account, etc.).

Can I do this in OS X? If not, are there any third party solutions I can use?

You could create a screensaver using the video file so that it plays while the screen is locked.

If you're code inclined you may even want to try writing it yourself: http://cocoadevcentral.com/articles/000088.php

Or alternatively, there are utilities that will do most of the work for you: http://iscreensaver.com
