Moodle has a built in video player called Flowplayer. Anywhere that Moodle's text editor is available, it is possible to embed a video. You can imbed a video in a label, a page, a course topic summary, a quiz description or a lesson. One exception seems to be if the video is an MP4 file.
MP4 files don't seem to play in Flowplayer.
