Where can I find Spanish or Latin American movies with Spanish subtitles?

I want to get movies like Los Amantes del C铆rculo Polar and Amores Perros in their original language with Spanish subtitles to practice my comprehension of the language but the versions I've found offer only subtitles in English.|||try to visit cupunista and lovechessy site,that site is about movie and also containing subtitle for download,but maybe not for all movie.. http://cupunista.com and http://lovechessy.info
