I have Amazon movie purchases downloaded to my Roamios'. I'm preparing to deactivate them and replace them with a new Roamio Plus. There was once a thread about Amazon purchases were someone stated that if you delete a Amazon purchase (and permanently delete it from deleted items) that such content will be available again to download later. Since there is a limit on downloads once a Amazon title is purchased, I'm reluctant to delete such as I'm not sure if I follow how Amazon knows if a title is permanently removed from a Tivo. Can anyone confirm?
