When the output is going to be MPEG-2 encoded. The "DVD" and "SVCD" presets
automatically set this. (420_JPEG is correct for MPEG-1 and MJPEG.)
As you may expect, the output mode will

The chroma planes are being scaled by (2/1, 1/2) and the luma plane is
getting (1/1, 1/1) (w

And here is another patch, to add the 4:1:1 mode I mentioned a few weeks ago.

Hi all,
In case you're interested, I've *finally* posted smilutils to kino CVS.

0.1.3 release).
Dependencies are reduced (gnome is gno more? almost true
