 @section I have a problem with an old version of FFmpeg; where should I report it?
-Nowhere. Upgrade to the latest release or if there is no recent release upgrade
-to Subversion HEAD. You could also try to report it. Maybe you will get lucky and

+Nowhere. We do not support old FFmpeg versions in any way, we simply lack
+the time, motivation and manpower to do so. If you have a problem with an
+old version of FFmpeg, upgrade to the latest Subversion snapshot. If you
+still experience the problem, then you can report it according to the
+guidelines in @url{http://ffmpeg.org/bugreports.html}.
