Just a quick warning based on my own personal experience: If you have an ATI All-In-Wonder Card and you attempt to update the drivers with the latest ones offered on ATI's website, the update will remove any macrovision hacks that you previously had in place.

Fortunately, it's not a major inconvenience as you can re-apply the old hacks after the new driver is installed.

I use the macrovision hacks offered on lordsmurf's website (www.lordsmurf.com). Thanks LordSmurf!
