How about removing the other addons I mentioned in the thread pointed to in my last post... before installing (not just AVControlSDK)? The QuickTime explanation was already there, in that post. You can try removing everything except the MF components.Any help would be greatly appreciated.
By "removing" I mean just move them somewhere else. You can move 'em back later and don't need to reread everything from the CD.
My bet is the failing install is due to one of the packages in WinDVD or DVDCopy (phone-home service, InterActual, Windows patches, or ASPI) if it is not AVControlSDK. Just a hunch based on previous experience.
