Try mencoder with a command line something like this:
mencoder -o foo.avi \
-ovc lavc \
-lavcopts vcodec=msmpeg4v2:vbitrate=256 \
-vop scale=240:180 \
-srate 32000 \
-oac mp3lame \
-lameopts cbr:br=32:mode=3 \
foo.nuv
This plays in Windows Media Player with the stock codecs and should be of
sufficient quality for handheld viewing. (I was using it to watch stuff on
my notebook while on the road last summer; the low bitrate made shows
downloadable in a reasonable amount of time.) I'd think that something that
plays DivX could play this too. I'd try it on my Tungsten T just to make
sure, but it seems to have gone into hiding. :-(
Encoding one hour of video this way takes 11-12 minutes on an Athlon XP
3000+. Your Celery is going to be slower, but I'd think it would still be
nowhere near 12+ hours. You'll probably get somewhere around one hour, or
maybe a little longer, for one hour of video.
