  A process created (I guess by the movie library) just died, and
  the default performer behavior is to exit the application if such
  a thing occurs.

  Try to do your own SIGCHLD manager by calling:
  sigset(SIGCHLD, (SIG_PF)Yourfunction);
  right after pfConfig();

  Or simply call sigignore(SIGCHLD)
