How do I add 2 different themes to a wordpress website? Please help?

I’d like to make a website with wordpress using the Gazette Theme from Woothemes as a general theme to the website. However, I’d like to have a section called "videos" (or something like that) with a videoblog theme like one of these: http://www.justskins.com/wordpress/6-brilliant-wordpress-theme-for-video-blogs-or-vlogs/371

how would i incorporate 2 different themes into 1 wordpress website? Is there any coding i can do or something?
