stupidly, I installed the DivX codec for quicktime without checking that it was the universal binary version. The site doesn't say, and I just assumed it was... stupid, I know. Anyway, I can't install the beta of the universal version (I get the message "nothing to install") without uninstalling the PPC DivX 6 that I installed. But while there is an installer script, there's no uninstaller script, and just dragging the app to the trash didn't do it. Any help please?
