Hmm, why have you removed the above paragraph.  Is it not correct
anymore?  I must admit I haven't read the MEncoder section in such a
long time that I cannot tell for sure right now..

As a matter of style, I prefer not to spread tags and tagged content
over two lines.  I find this easier to read.

I think long forms (it is) are preferred over long forms (it's) in
written English.

If I am not mistaken the 2nd audio track is 129, not 128.

Let's not further spread the false asssumption that Ogg and Vorbis are
the same thing and/or inseparable.  Just say Vorbis when you mean the
audio codec.

Please try to keep lines below 80 characters, or even better 60-70
characters so that if small changes are made later on they show up
nicely in the diffs.

What are you trying to say here?  Either you have the distinction
between containers and formats wrong or you are just writing it in a
confusing fashion.  A video or audio stream can be muxed into a file,
but not vice versa.

Nice work.
