It isn't specified anywhere regarding the supported output formats, but the developers also created an application that you can use to edit and import your recordings and then export them to various video sharing websites or on the DVD as well.
If you have the application installed, go to Help > Contents to read about the available ways you can record as MPEG. I believe you will find the MPEG format in the Save as or Export menus.
Additionally, look in the installation folder as well for user guides and tutorials.
