After losing the high-definition DVD format war to Sony’s Blu-ray, Toshiba is digging in around the standard definition DVD market. The company has launched a new upscaling DVD player, the XD-E500, which promises to bring standard DVD quality closer to high-definition than ever before. The company has even launched a new Web site to help show consumers about the new player and a new upscaling technology that runs on it. Toshiba’s new $150 XD-E500 features Toshiba’s new eXtended Detail Enhancement technology.
