GarageBand Movies into iDVD

I have some movies edited in iMovie and chaptered in GarageBand. I want to use iDVD to burn them. Now here is the catch... I can share any one of them from GarageBand to iDVD and it automatically creates the chapters and menus. What I want to do is share another one to the same project.

Now this sounds easy, but in iDVD's Media Browser the GarageBand movie files don't show up under the Movies tab, even if I add the GarageBand folder to the list of sources. The files do show up under the Audio Tab, but only as Audio files -- I can't add them as movie files.

Is there a way in either GarageBand or iDVD to allow you to import/add a GarageBand movie file into iDVD without using the "Share with iDVD" option from Garageband? Am I missing an export/share option somewhere?
