Thanks.  Compiled ffmpeg myself:

built on May 23 2011 22:32:40 with gcc 4.4.5
  configuration: --enable-gpl --enable-version3 --enable-nonfree
--enable-postproc --enable-libfaac --enable-libmp3lame
--enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora
--enable-libvorbis --enable-libx264 --enable-libxvid --enable-x11grab
  libavutil    51.  2. 1 / 51.  2. 1
  libavcodec   53.  6. 0 / 53.  6. 0
  libavformat  53.  2. 0 / 53.  2. 0
  libavdevice  53.  0. 0 / 53.  0. 0
  libavfilter   2. 10. 0 /  2. 10. 0
  libswscale    0. 14. 0 /  0. 14. 0
  libpostproc  51.  2. 0 / 51.  2. 0

And turned it into a Debian package:  ffmpeg_201105232235-git-1_i386.deb.

Uninstalled then installed above.  Still have same problem.  Is there a
simple way to get hold of appropriate presets, perhaps?
