Just a few shots in the dark, but might be helpful:

I would try to make a clip as close to that sample file as possible and
try to get something that plays, then work backwards to find what
particular attribute the Archos doesn't like.

Use -ovc divx4 and -ofps 25 and see if that works. If you don't have the
DivX5 libraries, try using lavc and setting the fourcc with -ffourcc
DX50. You can also try -lavcopts vstrict=1 and see what happens.

Good luck,
