Template overrides are a way of changing the way WordPress shows something without changing the extensions or core WordPress system. That's important because it means that as WordPress and/or extension is upgraded to new versions you will not have to repeat all the changes you made.

MiwoVideos strictly uses the WordPress override system and comes with 3 overrides by default in addition to the default one; YouTube, Vimeo and Dailymotion. So you can set the view of MiwoVideos just like these popular sites.
