Are you using codecpacks (Lazy Man codec pack)?
If so uninstall it and then install DivX 5 (or 6 if you want and you have WindowsXP) and enable the option to decode all the FourCC video contents.

If you need to know where to find codecs for which video format, thake a look at adicoto's list of codecs

Do not install any DivX Networks bloatware.

Use FFDSHOW to decode most MPEG4, including DIV4.
