yes and no, it is indeed a very old version of mencoder, but still the
most recent one, that is available as a binary. you also find _very_ old
binaries in many distros.
actually, it is not more than a few weeks, probably months ago, since
-lavfopts was fixed and the option 'i_certify...' disappeared, so this
is not a sign, that a _very_ old version is used here.
however, compiling mplayer from svn-sources is highly recommended,
because bugs usually get fixed quite quickly and more recent version can
be considered to be even more stable than old ones.
