TiVo owners who enjoy doing more than just recording TV shows just got another on-demand option. Walmart's video service, Vudu, will be available on select models soon, bringing over 100,000 movie and television selections for rent or purchase à la carte. In addition to feature films, Vudu serves up TV shows from CBS, Comedy Central, HBO, MTV, Showtime and more. Of course, the service is already available on the web, iOS, Android, Roku, Playstation, Xbox, smart TVs and Blu-ray players. The Vudu app is set to hit TiVo Roamio DVRs and the TiVo Mini "during a rolling update" in the next few weeks.
