Movie Maker 2.1.... audio issues

For info.... numerous attempts to install SP3 on my XP laptop failed...
after which I found myself with a number of MM2.1 issues with audio files. I
got a 'class not registered' error when trying to open the narration
feature, couldn't play existing wma files in the collections, got error
messages about wma files not being valid or corrupt when trying to import
them, and the picklist of options in the narration window were gone. The
files on the hard drives played fine in WMP.

All were resolved by re-registering QASF.DLL in the system32 folder. I added
this comment to my website on the Problem Solving > Audio Issues page.
