The analogy falls down exactly at the point of my question, because MS
Word format is not documented at all reasonably.  It also falls down
otherwise since Emacs has a builtin info reader, but no builtin Ogg
Theora reader.

So you make up a strawman which has absolutely no usable connection with
my question or Richard's statement and then sneer at it.

That's all very nice, but I am still interested about the original
question.

One problem that I see with Ogg Theora that it is intended, as far as I
know, for real-life movies.  Just like JPEGS are rather unsuitable for
screen shots when compared to well-made PNGs (except when a large amount
of screen is covered by a photograph) because of a lousy tradeoff
between artifacts and compression ratio (PNGs tend to be quite smaller
and sharper), I'd expect Ogg Theora to be similarly encumbered for
screen animations.

Feel free to point out when I am mistaken.  But please try addressing
what I have been saying instead of something else.
