I was also wondering if there was a codec package where I can download the Windows Media codecs. I really don't want to rebuild the install and reinstall my whole OS. I don't have any more CD's lying around and I don't have time to go out and buy. So I was wondering if anyone knew of a way to add the WM codecs back or a site to redownload them. I also tried using CCCP (www.cccp-project.net) to play the WMV files but MPC is unable to render the videos, so I'm guessing I would still need the codecs even if I do have ffdshow installed.
