[Encode2mpeg-users] quality options in mpeg mode

[Osmany G. C. <osm...@ci...>]

Hi
   I am using mpeg mode to do (s)vcd and i am using -encode 4:4:1  i use
*:4:* to get quality but i do a ps aux | grep mencoder and saw this
options...
:mbd=2:mv0:precmp=6:cmp=6:subcmp=6 
i want to know why not include other options like v4mv , dia=? , dc=?
or if with this option it's "OK" to get a good quality film...... 

Thanks 
Osmany
