Your question really doesn't have anything to do with your goal, at
least for the functions you've referenced. The dataRef is an arbitrary
handle, and the dataRefType tells the function what kind of information
to expect to find at that handle.

You want this function, which I found at
<http://developer.apple.com/technotes/tn2005/tn2140.html>.

OSStatus WriteFlattenedMovieToFile(Movie inMovie, CFStringRef inPath)
{
   Handle    dataRef = NULL;
   OSType    dataRefType;
   OSStatus  err;

   // create the data reference
   err = QTNewDataReferenceFromFullPathCFString(inPath,
kQTNativeDefaultPathStyle, 0,
                                                &dataRef, &dataRefType);
   if (noErr == err) {
       // flatten the movie
       Movie newMovie = FlattenMovieDataToDataRef(inMovie,
flattenAddMovieToDataFork,
                                       dataRef, dataRefType,
FOUR_CHAR_CODE('TVOD'),
                                       smSystemScript,
createMovieFileDeleteCurFile);

       if (NULL != newMovie) {
           // we choose not to do anything with the returned movie
           DisposeMovie(newMovie);
       } else {
           err = invalidMovie;
       }

       // remember to dispose the data reference handle
       DisposeHandle(dataRef);
   }

   return err;
}
