For those who use(d) my list...
The link to the download page of KB904706 (Vulnerability in DirectShow) was for a version that's only intended to be applied on Windows XP with Service Pack 1. The new download link is for the version which is intended for Windows XP with Service Pack 2 as well.

Windows Update didn't complain when integrating the "wrong" version of the update, but HFNETCHK would claim that the version of quartz.dll is less than expected.
