I was under the impression that if you disable LW's media player & make wmp the default, that it would import them. Perhaps if & only if you launch/play them in it. The other option I guess is to direct your wmp to the LW dwnld folder & import them. LW's Dwnld folder can be found here: LW's menu Tools>Options>Saving which will tell you the name, location & path of this folder.
