Hi, All,

      When I use debug mode of version 1.2.2, always get problem at mbcoding.c (in folder \bitstream) :

 if (!pMB->mcsel)
  for (i = 0; i < (pMB->mode == MODE_INTER4V ? 4 : 1); i++) {
   CodeVector(bs, pMB->pmvs[i].x, frame->fcode);
   CodeVector(bs, pMB->pmvs[i].y, frame->fcode);

#ifdef _DEBUG
   if (i == 0) /* for simplicity */ {
    int coded_length = BitstreamPos(bs) - bits;
    int estimated_length = d_mv_bits(pMB->pmvs[i].x, pMB->pmvs[i].y, zeroMV, frame->fcode, 0);
    assert(estimated_length == coded_length);
    d_mv_bits(pMB->pmvs[i].x, pMB->pmvs[i].y, zeroMV, frame->fcode, 0);
   }
#endif
  }

estimated_length IS OFTEN NOT EQUAL TO  coded_length.   so assert error always happen.
Maybe latest version should modify this code....
