Error News Pagination

first, I'm sorry for bad english. I'm using google translator.

I have a website with a page of videos and exclusive use for the CuteNews posts:

http://www.mundootaku.com.br/index.php? … /principal

My problem is when I try to go to the next page of videos he directs me back to the main page.

Can you help?

Another problem is when I try to access the page via the link of the RSS, he also appears error.
