skip motion estimation and encoding of non direct-0,0 MBs if the next MB is skiped (mpeg4 doesnt allow such MBs and in the past we did ME and encoding until at the end we droped them, so this should be faster though i didnt benchmark it, benchmark welcome)

  some PSNR/bitrate gain if adaptive quant is used
initalize qscale_table correctly (it was pretty much random since the qp->lambda change)
  this probably has not much effect as the table isnt used currently IIRC
