Okay.  I don't really have an interest in the standard.  I only mentioned
it because that's how Carl responded.

That's really what I want to know.  Can mencoder output YUV422 pixels
with it's "mpeg4" encoder?  If not, can ffmpeg output YUV422 pixels
with it's "mpeg4" encoder?  (I know this isn't the place to ask ffmpeg questions
but it's easier to ask that question now then start a whole new thread on the ffmpeg
or libav mailing list).

Why do I want to know?  If the answer is "no" for mencoder and ffmpeg, then I can 
forget about trying to do editing, inverse telecining, and mpeg4-encoding in YUV422
format and move on to the next project.

Well, Reimar implied that it doesn't.  I'm confused.
