Nero 7 DVD Video vs DVD-VR Project?



Does anyone know if a Nero 7, Vision 4 project started as DVD Video (VR) can be converted or reopened/re-started as a DVD Video project?

My problem is that I started a project as DVD-VR and at time of making a burn found out that burn to Hard Drive and Image is unavailable. Is that normal? If burn to Hard Drive and Image is not supported in a DVD-VR project, can this project be re-initiated as DVD-Video without having to start over entering AVI and Audio clips?

Thanks for any feedback, Joe
