Get smaller video in YouTube Featured Plugin

The YouTube Featured Video Widget isn't listed so I just picked Terms of Service plugin.

OK -- forget it... by selecting the "Play in a pop-up window" it auto resized, fixing the problem.

Not the fact that I couldn't select the plugin from the list of installed plugins
But the fact that until I selected the "Popup Window" box... the video was all screwed up in that column.


So, take a look...
Right Column has YouTube Featured Plugin.

Want to make the video display smaller so it doesn't present the way it does currently.

Where do I set the size parameters?
