How can I locate a keyframe in a DivX stream?

Hi guys, major video newbie here.

I'm encoding DivX 3 video using ffdshow, and I'm encapsulating it in Matroska. I'm using mkvmerge, a Matroska utility, to pull the DivX stream out of the container. What I'd like to do is read the stream and locate the keyframes. However, I haven't found any luck finding information on how frames are encoded, other than that DivX 3 is based on Microsoft's MPEG-4 Version 3 codec.

Can anyone offer any tips? I couldn't find much when I searched the board.

Thanks!
