Everytime I try to look up cover art in Media Center for old rips that are missing it, Media Center doesn't find anything (or it only finds whatever cover art is already there for those rips that already have some).
Am I doing something wrong? Can Media Center look up different selections of cover art for rips that have none?
If it can, do you need to do anything special other than select all the files and the option Cover Art/Get from Internet?
