Pjuol,

I'm not an xvid developer, but I'm currently also working on a PalmOS port; 
for an open source media player project 
(http://sourceforge.net/projects/magiclantern/).

In my experience the biggest problems are the use of global variables and 
large memory allocations.  By moving much of this out to resources and 
trimming other bits of code I've got it working reasonably well at the 
moment.  Most of the code seems nicely portable if you put the right stuff in 
portab.h and include definitions of endianness and size.

Obviously the other changes you'll need will be the obvious things you mention 
like reading the file, drawing the screen and so on.

Hope that helps a little.
