Hi !!!

Can you tell me where can I find info about what are luma, chroma, single 
coeff. elimination? I find your comments are very interesting, and other
people told me about this options in the past too; but I don't know what
they are. I look for it in the docs; I found suggested values but nothing
more (I understand that docs are about mplayer/mencoder not about codecs
in general, of course)

Thanks in advance,

Martín
