David, Sorry for the late response, I've been offline the last few days.

Later, I did remove QuickTime entirely and re-install V6.5.2 (with > no iTunes) from a file I already had on disk. This points to the problems with Windows time if a multimedia application is started. I've mentioned this sometimes before here in the newsgroup, e.g. here: http://lists.ntp.isc.org/pipermail/questions/2005-September/006709.html This problem is NOT from the MM apps themselves but from the way Windows is keeping time, and AFAIK has been fixed by MS in SP2 for WinXP. So you won't fix the problem by using another version of ntpd. Either you must make sure no MM app runs at all (maybe even not in the background, if QT looks if updates are available), or you must have at least one MM app running continuously in order to have the MM timer set constantly set either to highest resolution or default resolution, but not switching between the 2 resolutions. If the MM timer is set constantly to high resolution then you should observe a little more jitter than with default resolution, but the large steps should go away. So as a test you just might to start Quicktime ant watch if the offset settles down.
