Authoring divx for set-top dvd-player



hello all. im looking to purchase a set-top dvd-player that plays DIVX files, im wondering is there a DVD-menu authoring program that would allow me to create frontends for my DIVX movies, so they look kinda almost-professional, “sorta”? or how about this: if DIVX files are considered .avi, and i hear there are authoring programs that would let me author those files-types, shouldnt this work as well? if this can be done, can anyone recommend any authoring software that would allow you to do this? thanks in advance for your aid/assistance.
