I put the ffmpeg formula into a script that basically converts all my
recordings into mp4 for playback in mythweb.  I put the converted files in a
separate partition and symlinked it to my mythtv recordings partition.
Works with the ipod internal player through safari as well as the  mplayer
plugin in firefox on my laptop.  Its amazing how the quality is so much
better than flash which I used before.  The behavior of mplayer plugin is to
download the entire file before playback so I can have three firefox windows
each with mplayer plugin running and since it is configured to use esd, I
can switch between windows or play them all at the same time (obviously no
practical use. ) I have a couple of machines doing the transcoding currently
and after about a week, I think its transcoded 60 % of the files.   If
anyone is interested, I can upload it.
