Changing Render Type in Render Settings (Solved)

It seems like it should be possible to change the 'Render Type' selection to 'Image Series' or 'Movie', but I have yet to figure it out.
Using DzRenderOptions, I can change some of the values in the Render Settings panel, but not the Render Type.
I'm beginning to suspect that I need to use other classes, such as DzPane or some other interface. Can anyone help me out?
