I've seen that too.  I've also seen that the blocks are divisible by "16 or 32".
486/32=15.1875 or 30.375

mpeg2enc.c:85
/* round picture dimensions to nearest multiple of 16 or 32 */
mb_width = (horizontal_size+15)/16;
mb_height = prog_seq ? (vertical_size+15)/16 : 2*((vertical_size+31)/32);

Of course, these are NTSC numbers.  Our PAL buddies get better resolution.
