Nevermind. Found the following on Google which applies to WINXP.
I'll bet PD7 installes a certain number of Codecs so be careful not to remove them. Otherwise, you'll need to re-install.
*********************************************************
To remove a video (or audio) codec goto your OS Device Manager -> Sound and Game Controllers -> Right-Click on Video (or Audio) Codecs -> Click on Properties -> goto the Properties tab. The list of codecs will appear. Hi-Lite the one you want to remove and click the Remove button.
