Comment (by Dan203):

 This should fix it...

     /* Determine the codec's field order from the packet */
     if ( *vsc_pack == dv_video_control ) {
         s->frame->top_field_first = !(vsc_pack[3] & 0x40);

         // Reference field order is reversed in SMPTE 370M spec for HD
         if (s->sys->height > 625)
             s->frame->top_field_first = !s->frame->top_field_first;
     }
