I see. Had a couple of follow-up questions that are related to this
matter.

I've noticed that when I import MS-DVR files into Windows Movie Maker,
I get audio, but no video.

1. Is it possible that the later ATI driver might fix this?
2. Is it worth the risk of installing a driver that's not Windows
certified?
3. If you're not able to use Windows Update, how do you uninstall the
old driver before installing the new one?

Thanks!
