1) Official DivX codec: www.divx.com/divx/download

play .avi sound properly (current version 5.2.1 for Mac OS X and 5.1.1
for Mac OS 9)
2) 3ivx codec: www.3ivx.com/download/macos.html

the fastest MPEG-4 codec for mac (current version D4 4.5.1)

And that's it! Now you can play all standard DivX movies files with
QuickTime without problems! There is no need for DivX Doctor or any
conversion. Just open .avi file with QuickTime. There might be some
extremely rare cases when wma (window media audio) codec is used in
.avi's. Then you can try DivXWMAConverter:

Why should I use QuickTime when I can use VLC or MPlayer?
· Using 3ivx video decoder, the CPU usage is lower compared to VLC or
MPlayer. Useful for older Macs with G3 CPU or if you are running other
processes that uses a lot of CPU while watching DivX movie.
· You can play, edit or export DivX movie with ANY software that
supports QuickTime
· You can play DivX movies with Mac OS 9. All of these three
QuickTime components (codecs) are available for Mac OS 9 and Mac OS X.
If your Mac has less than 400Mhz G3 CPU you may want to restart to Mac
OS 9 because there you will get a bit better results.
Subtitles:
You can also add Subtitles for your DivX movie using TitleLab and
QuickTime Pro: www.azinesoftware.com/titlelab.php
TitleLab comes with good tutorial how to convert subtitles to
QuickTime text track and how to add the text track to DivX .avi
