	I don't know anything about "multimedia timers", but Windows is 
known to be seriously broken when it comes to dropping interrupts, 
etc....  You will find that ntpd does what it can in the face of such 
serious problems, but there's only so much it can do.

	If "multimedia timers" cause such problems for you, is there a 
particular reason you use them?
