Frame by Frame video program like Quicktime

This is really stupid, I just want to watch an animation video file to see how they did it, movement wise and it's in Divx format but Quicktime claims it doesn't have the Divx codec (I'm on Windows XP and all the other programs work correctly with Divx) Is there, either a way of installing Divx for Quicktime or another program which will allow me to watch an animation frame by frame without putting it into an editior like After effects. I mean I thought Media Player would have had this build into it, it's not like cutting edge tech. or something.

Thanks in advance for all help.

Windows Media Player is not the thing to expect features from. Pretty much every decent video player supports frame by frame. Try BSPlayer or Micro DVD player or Virtual Dub for example. You may not be able to watch the movie frame by frame even with a more advanced player and you will need a video editor. I think it's the encoding style of some codecs.
