strange behaviour with my TransitionTrackBuilder mod

Really unusual scenario(bug??) I spent too much time narrowing down.  I was playing with the TransitionTrackBuilder from Chris' QTJ Notebook.  His code works fine of course.
 
Now, to save the finished movie, the code reads:

        OpenMovieFile omf = OpenMovieFile.asWrite(movFile);
        movie.addResource (omf,
                           StdQTConstants.movieInDataForkResID,
                           movFile.getName());
 
movFile was defined previously in creating the blank movie that all the tracks were added to:

QTFile movFile = new QTFile (new java.io.File("C:\\Tests\\translations\\transition.mov"));
        Movie movie =
           Movie.createMovieFile(movFile,
                                  StdQTConstants.kMoviePlayer,
                                  StdQTConstants.createMovieFileDeleteCurFile |
                                  StdQTConstants.createMovieFileDontCreateResFile);
 
Like I said, this all works fine. 
 
Now, if I make a small change and write the movie out this way instead:
 
QTFile qtf = new QTFile (new File("C:\Tests\transition.mov");
movie.flatten (0, // movieFlattenFlags
                             qtf, // fileOut
                             StdQTConstants.kMoviePlayer, // creator
                             IOConstants.smSystemScript, // scriptTag
                             StdQTConstants.createMovieFileDeleteCurFile, // createQTFileFlags
                             StdQTConstants.movieInDataForkResID, // resId
                             qtf.getName());
 
Not surprisingly, this works almost exactly like Chris' way.  The maddening difference is that there's a little 'tick' of white space introduced between the first clip and the beginning of the transition.  I've checked and double checked, and narrowed it down to the above difference.  Somehow, the track offset information seems to be getting slightly askew when flattening the movie as opposed to saving it back into the resource file.
 
What's going on?
 
The sample movie I'm working for both start and end movies can be found here:
