I tried that and it didn't fix it. Or do I have to restart to fully reinstall the codecs? I don't want to do that right_now as I'm seeding a torrent.

Also: one of the files inside MSI.CAB (in the MP3 Player Utils Installer) is regarded as a virus by Kaspersky 6, although I'm sure it's mistaken. As you know, the software comes on the driver CD with ChiPods, it did on mine, but an old 3.0 version - which led me here in the first place.

However, the virus on my ChiPod was definitely a virus.
