Exporting movie from iMovieHD back to mini-DV

[Satisfactor]

Hi, I've been trying to export some of my old home movie originally imported in iMove 2, and updated through iMovies ending up with iMovieHD back to my Sony mini-DV cam, as a tape-back up for the edited movie. Everytime I try this, it seems to crash. Same problem with PowerBook G4 and iMac G5, both running latest OSX. Do I need to by a HD camera now to be able to do this?

Doesn't it stand to reason that your export should be in a format that your camcorder understands?
