Apple Pro Video Updates: Endless Repeated Updates

Just another example of Apple Core Rot. This is the 5th time the system is asking to update the Pro Video formats
MPG: the 4th repetition for me. But I was gone for two days, or I’d be up to five or six I suppose.
UPDATE: see fix below.
UPDATE 2: the fix does not work.

Apple software update repeatedly wants to update the same thing (Pro Video Formats)
Fix (does not work)
It’s an absurd situation of course. Why Apple does not monitor updates and immediately take corrective action is unclear.
An Apple discussion goes into a workaround. Here is what worked for me, using Terminal. The '#' line is a comment.
cd /Library sudo mv QuickTime/ QuickTime.save # install and/or do the update, no reboot needed sudo cp -r QuickTime/*.component QuickTime.save/ sudo rm -rf QuickTime/*.component sudo mv QuickTime.save/*.component QuickTime sudo rm -rf Quicktime.save
