Yes, I think I've got there.  The 'old, non-existent videos' persisted 
because their host no longer had a Video SG. It wasn't scanned, so the 
list wasn't updated.

So I had to re-create an empty VSG on that host and rescan, and then 
re-delete that VSG.  Now the Video list seems sane and the scanner no 
longer says it hasn't found the extra VSGs.

Thanks for your help.

This is all rather off-topic, but I expect Google will notice it.  And 
the Subject topic has been fixed :-)
