The rules only apply to new media - existing media ID's will not be 
changed, and as far as I know, there is no way to modify these. You can 
delete the ones with the undesirable ID's from your database if you 
haven't used them and when you add them again, the new rules should 
generate the proper ID's.

Hope this helps
