Get rid of the new IDE drivers. I didn't know about the "parking" issue, but they broke my Quicktime playback pretty badly. I got lots of stutters in the video playback on large files like the big version of Animatrix web cartoons, and a friend at work got the same issue with his machine when he tried the new drivers as well. I switched back to the old MCP2 driver and life was good once more. We'll probably see a 2.43 version soon with fixed drivers.
