Do you mean like a video site like youtube?

4. We do not allow any video, image or file hosting / sharing scripts to be run. (allowed if you upgrade account)

Now if it was just one video, you may be able to go with that

As Sizzlefire said, you cannot host video. But, you could code a comment feature or use http://js-kit.com
