Just a note to thank everyone on this thread for the help / advice contained here. My RH1 started running slowly after Sonicstage had an encounter with a NH900. I ended up deleting everything, including Registry USB's Hidden devices etc and re-installing. The after 3 attempts it finally condescended to load the Net Md Driver. I wouldn't say it's flying but so far it's quicker than re-recording SP to Hi-MD. The only thing I didn't try was Avrin's .inf suggestion. Incidentally, I never encountered this problem before I switched to Vista. Sony must REALLY hate their customers!
