DSLocalizator localizes only portal, tab and module PROPERTIES. For content localization you have the following options:
1) To get a module that supports localization by itself
2) To use DSLocalizator to hide an instance of a module based on the selected locale. You can drop two instances of the same module type into a page, then you can tell DSLocalizator to hide one instance per language and just fill the content of each module depending o the visible lenguage.
Hope it helps
