Help Installing Mediaplayer 10 Beta on Server 2003

[Chem]

Fallowing These directions for installing Windows Media player 10 in the latest Longhorn alpha, which claims should also work in server 2003, I can't install any of the *.inf files because of Server 2003's strict driver signing/Logo testing bulls***.

I try to manually turn off the driver signing/logo testing via system properties in the control panel, but no matter how many times I change it, as soon as I go back to it there’s no change.

Anyone know of a solution?

Or a way of manually turning off the driver signing with a registry edit or something?
