I don't know what you mean by 'passthrough video', except that it must
mean that it skips postprocessing. :) 'Passthrough' is mentioned once
in the manual, with regard to AC3.

Yes, the manual is better now. Thanks. Still.. If someone has
extra time and described what the different knobs really *do*, it
would be even better. Like, I'd like to know what mbqmax is supposed
to be doing, and how it relates to lmax and vqmax.

That didn't help. First I tried exactly what I think you suggested:

mplayer -vo mpegpes -ao mpegpes -vc mpeg12 -vf spp=6 whatever.avi

It said "Cannot find codec matching selected -vo and video format
0x58564944", and exited.

Then I tried it as follows:

mplayer -vo mpegpes -ao mpegpes -vf spp=6 whatever.avi

This succeeds better. I get video on the TV. However, it doesn't
do any postprocessing. I notice in the output (-v) that it
says "Opening video filter: [lavc]", so it seems we are back where
we started.

If I take out the mpegpes stuff as well

mplayer -vf spp=6 whatever.avi

It does filter correctly, and outputs on a window. And is
WAAYY.. slow. My Athlon XP 2500+ can seemingly just handle
spp=2.
