Nailing it down could be a big job.  The 0.6 branch diverged from trunk 
a long time ago, and I couldn't bring myself to root through all the 
likely suspects in the change log.  I checked random versions back to 13 
Oct 2010 (when 0.6.1 was tagged) and they all seemed to work. I believe 
the last version available to the get_iplayer Windows installer works. 
This is marked r26400 (17 Jan 2011), which is the  last version built 
from Subversion (thus the integer revision number) before the ffmpeg 
project moved over to Git.  I'm using version git-ae7a4a1 on OSX.  That 
is a HEAD build via Homebrew from 9 Apr 2011.  The ffmpeg project has 
cut a new release 0.6.9-rc0, and although it built OK for me on OSX, all 
it gave me were a load of segfaults.  The MacPorts and Fink builds are 
too old, so if you can use Homebrew (not a small thing, I know) and do a 
HEAD build you should be able to generate a pretty capable version 
without much sweat.  If you want to roll your own, start with the 
somewhat outdated instructions below and adjust to suit.
