Creating a PAL iMovie project

Wondering if anyone can help with this? I am using iMovie 6 and want to create a project with default PAL format but don't have this option when creating a new project. It allows selection of DV video format but then automatically defaults to a NTSC session. Does this mean that even if I import PAL clips into the project, once I build a movie by dropping these onto the timeline, the resultant iMovie will be NTSC with lower quality rather than PAL? Also, if I include photo images in the iMovie, are they converted to NTSC? Anyones assistance with this would be greatly appreciated.
