What are Vodcasts (Video Podcasts)? From Wikipedia.org
Video podcast (sometimes shortened to vodcast) is a term used for the online delivery of video on demand video clip content via Atom or RSS enclosures. The term is used to distinguish between podcasts which most commonly contain audio files and those referring to the distribution of video where the RSS feed is used as a non-linear TV channel to which consumers can subscribe using a PC, TV, set-top box, media center or mobile multimedia device. Web television series are often distributed as video podcasts.
