There are no lib*-unstripped packages available for 8.04.  Those are
8.10 packages.  Remove the following: ffmpeg, liba52-0.7.4,
liba52-0.7.4-dev, libdts-dev, and libx264-dev.  Then follow this guide:

Medibuntu will provide nothing you need unless you want AMR.  Medibuntu
also provides a binary of FFmpeg, but it is old.
