Another reason to host video or audio remotely is to give access to multiple formats of the file. EPUB3 has the capability of looking through a series of links and only using the one that works best in a given ereader. Including multiple versions of a video file in an EPUB file would result in unnecessary bloat. (Of course, this is a bit of a moot point in a world in which video and audio in EPUB mostly works in iBooks, but that is changing with Readium, and surely with newer ereaders. The fact that there is no agreed upon codec for video is also an important factor.)
