You may find the following lines in your HTKTools/HERest.c:

void GenDurMMF (HMMSet *hset, char *durfn)
{
  FILE *fp;
  char buf[MAXSTRLEN];
  int h,i,N,MaxN;
  Boolean isPipe;
  MLink mac;
  HLink hmm;

  /* vSize of dur MMF */
  MaxN  = MaxStatesInSet(hset)-2;

  /* ------- Output duration model ------- */
  if (trace & T_TOP)
     printf("Generatnig dur MMF from HMM MMF...\n");

  if ((fp = FOpen(durfn,NoOFilter,&isPipe)) == NULL)
     HError(7360,"GenDurMMF: Cannot create dur MMF file %s", durfn);

  /* output model definition and dummy state-transition matrix */
  fprintf(fp,"~o\n");
  fprintf(fp,"<STREAMINFO> %d", MaxN);
  for (i=1; i<=MaxN; i++)
     fprintf(fp," 1");
  fprintf(fp,"\n<MSDINFO> %d", MaxN);
  for (i=1; i<=MaxN; i++)
     fprintf(fp," 0");
  fprintf(fp,"\n<VECSIZE> %d <NULLD><DIAGC><%s>\n",MaxN,ParmKind2Str(hset->pkind,buf));
  fprintf(fp,"~t \"trP_1\"\n<TRANSP> 3\n");
  fprintf(fp,"0 1 0\n0 0 1\n0 0 0\n");

  /* output vfloor macro */
  for (i=1; i<=MaxN; i++) {
     fprintf(fp,"~v \"varFloor%d\" \n",i);
     fprintf(fp,"<VARIANCE> 1\n");
     fprintf(fp,"%e\n",minVar);
  }

It shows that if HMMs in your HMM mmf have more than 1 state (excluding null states), your duration mmf becomes multi-stream structure.
