Ok - both seem to be played without problems - the WARNING just shows
that whoever created this file ignores the standard structure size
which is 56bytes....

Well I would have say the DivX4 is simply broken.

You could select decoder via player - I must admit that proper setting
of this options is not documented and should be probably improved a lot -
but again all I could say - two hands are just not enough...

The problem only appears when you are reusing the codec.

It has nothing common with them - I guess it has only served as primary 
inspiration

I've thought this is just another project which is implementing
codec by itself - like ffmpeg or DivX4 and it shuoldn't have nothing
common with decore/encore.


BTW - I think you are missing one software to encode DivX4 files - 
mencoder (part of mplayer project)
- if you want to see valid DivX4 file - try this one.
