hmm, I actually ment to _base_ the manpage on the tech/* docs.
Shouldn't it be that the manpage is a subset of the particular
tech docs? On the other side it is even better if the developers
themself write the actual manpage section (as long as it's
"user-readable" ;)

hmm, I don't like it but maybe/probably you're right. I just hate
separated docs and like the way it is now. Also I don't think
it's necessary to include all aspects of the options in the
manpage (for example chroma skipping in -vop scale), maybe in a
guide section where they are needed. I have a new idea:
Keep it the way it is now and (in future) move all recommend messages
(use this for this, this is a good choice, this is fast, what to do
in which cases, bitrate?,..) to a encoding guide. Maybe with separated
sections (dvd, vcd (mencvcd), tv, ..., donno).
I'd say it would be a really BIG help for many. Afaik there's no guide
like this available for linux and you just have to know the things to
get really good results. For Windows there's the doom9 forum etc.
There was such a guide around on the user ml (for dvd) but it was not
really enough at all (imho). Any volunteers to create such a guide?

I more like centralized examples of _basic_ really often
used things, they belong in a manpage IMHO as it's the first
place someone looks at. Otherwise users have to search them
in the whole documentation which they probably won't do.
But I agree for specific long guides (dxr3,dvb,tvout,etc).

I don't know enough and I fear to touch the TODO file. ;)
(Maybe I will do sthg like this outside the main cvs on a
webpage -> comparsion)

I know, I just would have liked a general interface more than
all those variants. And sorry, I have to consider all those pp
autoq change outputs (with -quiet!) as a bug (hmm, forgot to report ;).

Can't it be used to inverse colors? (someone wrote about crpyted

> huh?
IMHO the patch rules should include one which say that cosmetics
in the docs are allowed as long as they are clearly separated by
the real changes. The example bellow replaced all '>' with the
html version '>' to avoid a broken html. If you translate,
it's easier to just follow the rules of the cvs comment than
browsing all changes and find it out yourself.

:)
I just remember the question I wrote the first mail for (I didn't
even include it ;)):
Where is the "-value w/h = original+value" vop parameter
description from? I haven't found sthg like this in vop.txt and
now I'm not sure if it applies to all w/h params, if it doesn't
exist of if it's only for scale.
Oh, and could someone check and comment the manpage patch? If I
get an ok, I'll commit...
