[MPlayer-DOCS] Mess in mencoder.xml's examples

I've found that examples in mencoder.xml (and probably
encoding-guide.xml as well, but I haven't examined it yet) are in a bit
of mess. So:
There are two examples of two-pass encoding. One with copying audio and
one with reencoding it. Can someone tell me why in the first output from
first pass goes to /dev/null and in the second to output.avi? IMHO it
should be /dev/null both. And while we're at it should the /dev/null be
in <replaceable> tags?
First example of mpeg output - the input file is named media.avi instead
of usual input.avi.
Second example of mpeg output (the minimal support one)
output file is x.mpg, should be output.mpg, and there's an ugly
line break between -o and name, while the next line is waay longer. It
goes like this:
mencoder -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 -o \
x.mpg -oac lavc -ovc lavc \
-lavcopts acodec=mp2:abitrate=224:vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3 \
While IMHO it should either be:
mencoder -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 -o x.mpg -oac lavc -ovc lavc \
-lavcopts acodec=mp2:abitrate=224:vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3 \
or at least
mencoder -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 -o x.mpg \
-oac lavc -ovc lavc \
-lavcopts acodec=mp2:abitrate=224:vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3 \
the PNG encoding example has only mf:// as source, I doubt it will work.
mf://*.png is better.
And there is a mess whether the general layout is
mencoder <input> <options> or mencoder <options> <input>.
Which one is preferred?
