Better mux to the MKV container.
Download mkvtoolnix and use mkvmerge to mux.
PS: Haali Matroska Splitter or equivalent is needed to play mkv files.

Make sure you can play AC3 files as well.

but i wanted to play it on my divx ultra 5140...

When I saw that qpel thingy, I thought, it couldn't be that he needs standalone compatibility, but then if you say you have the 5140, it's another story.

Well, it's been a long time I ever muxed AC3 w/ AVI, so I forgot how to do it correctly, but here what my google search has given:
In VDM, change both Preload and Interleave to:
160ms if it is a 384kbps AC3
128ms if it is a 448kbps AC3
Put the MP3 track as second (here you don't have to change the preload and interleave values, keep the default values).
