This document discusses different methods for playing videos in HTML pages, including using the <embed>, <object>, and <video> tags. It also covers using hyperlinks to link to video files. The <embed> and <object> tags can be used to embed multimedia like Flash videos, while the <video> tag, new in HTML5, allows embedding videos in different formats like MP4, Ogg, and WebM. Problems include needing different video formats for compatibility and older browsers not supporting the <video> element.
