You can find a newer version of Graphedit (directx9 compatible ,but not taken directly from SDK) ar In a few words ,it's a develloper's kit to make directshow filter graph s and play every media supported from an activex window,or ever extract tha graph for use with zoomplayer.MediaPlayerClassic(by Gabest) doesnt need graphedit to work-it's very easy to use and quite stable now
