Look in the table ezurlalias. The field source_url shows the url_aliases and the field destination_url shows the node (content/view/full/186) in the old fahioned way.
Hi,
in 3.3, the node and content IDs are printed "readable" in the admin interface... At least for the "content" tab, i'm not sure about the media tab. Plus, you should be able to disable "URL Translation" completly in 3.3, which should give your the "old-fashioned" URLs. Probably, this can be done just for the admin-site, if you wish, but changed the variable "URLTranslation" in a site-design-specific override.
