possible to import iDVD themes into DVDSP4?

Hi, and thanks in advance for any insight...

Is it possible to import an iDVD theme into DVDSP4? I really like iDVD theme in 6.0 called "Reflection". Is there a way to being it into DVDP?

The DVDSP templates don't have much choice. Is there a site for purchasing DVDSP templates? The Google search I did came up with nothing moer recent than 2006.

Thanks much,
Reuven
