I try without dc, cbp, mv0
output MPEG2 file also not fine :(

I read 
http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html#menc-feat-vcd-dvd
and try all examples therein for DVD PAL/NTSC format :(
Result - still more "light green square blocks"

Best result with: 
(http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html#menc-feat-vcd-dvd-lavc-advanced)

 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=8000:\
  keyint=15:trell:mbd=2:precmp=2:subcmp=2:cmp=2:dia=-10:predia=-10:cbp:mv0:\
  vqmin=1:lmin=1:dc=10

Best regards,
Gennady
