A month or two ago on joyride I had gnash playing youtube videos with
perfect sound, but very slow (.5ish FPS) video.  For sound (and maybe
video) you probably have to install the ffmpeg-gstreamer, and
gstreamer-plugins-bad (and maybe gstreamer-plugins-dirty), all from
the Livna repositories.  The problem is that we've reverted to using
an older version of gstreamer to get correct record behavior, and the
livna gstreamer-plugins want the newer gstreamer.
