VUDU is an online video store, owned by Walmart, through which you can rent and purchase film and television content.
Pay-per-use services like VUDU and iTunes generally receive titles on the same day they arrive on DVD, while subscription services often have to wait a much longer time to receive big-ticket home-video releases. VUDU titles are usually available at three quality levels: SD (480p), HD (720p), and HDX (1080p). You need a high-speed Internet connection to use the VUDU service; the company recommends a speed of at least 1 Mbps for SD, 2.23 Mbps for HD, and 4.5 Mbps for HDX.
