Absolutely agree.
A few interesting facts about Mercurial:
 - size of the whole ffmpeg history: 14 MB
 - size of a working directory (ie. the whole history + a full checkout):
   27 MB (to be compared to the 29 MB of a svn checkout which contains no
 - comparable speed to GIT
 - less complex than GIT
 - much better support for some plateform (namely win32) than GIT

For interested people, I maintain a Mercurial conversion of ffmpeg
repository available here: http://hg.gnuage.org/ffmpeg
You can simply grab it with: hg clone http://hg.gnuage.org/ffmpeg
Note that it has the same problem as the GIT conversion: it don't
include svn:externals.

For those who want to know a bit more about mercurial, you will learn
most of what you need in something like 1/4 hour in this tutorial:
And if you want a detailed documentation:
(BTW: AFAIK Mercurial also have a better and more complete documentation
than GIT)

Has you may have understood, switching to Mercurial would makes me very
happy, but I would already consider GIT a great improvement over SVN.
