Is it possible to have a fullscreen button on a video within Flash?

I have an external video playback in a website I'm making in Flash with actionscript 3.  Is it possible to create a working fullscreen option for that video?  I noticed some of the skins have fullscreen buttons but that don't actually work when you click on them.  Ultimately I wanting to make my own fullscreen button but if the preset ones don't even work I'm wondering if it's even possible.

Thanks.
