Usually video codecs in the AVI container will be identified by their fourcc (four character code) and audio codecs by their tag number. Once you know what you need, you can search it on the web and download and install it.
Quick reference should you encounter these:
Xvid: fourcc XVID - get it here
DivX 5 and later: fourcc DX50 - get it here
DivX 4: fourcc DIVX - get same as above
DivX 3: fourcc DIV3 and DIV4 - get it here
I wouldn’t really recommend codec packs, but if you must get one, get the ffdshow-tryout filters, or an all-in-one player such VideoLan.
Another thing to keep in mind is you may sometimes encounter incomplete, truncated, or AVI files of incorrect length (gspot will tell you). Windows Media Player can’t play those, even if you have the right codec. What you’d need is something like Media Player Classic or AVIPreview.
