"CyberLink Corp., a leader in Digital Home solutions, today launched PowerCinema Linux, providing an easy means of converting the Linux PC into a feature-rich TV entertainment center ideally suited for PC vendors targeting the CE market. The new PowerCinema Linux transforms a Linux PC into an entertainment center featuring analog and digital TV, radio, Teletext and electronic program guide browsing. A launch sequence of about 10 seconds and quick shutdown provide CE-like behavior on a notebook or desktop PC. The stylish 3D interface and operation by remote control ensure easy navigation of additional features, including DVD movies, music, pictures, and video modules."
There is an impressive list of features that this solution supports. I think this is the most polished solution I have seen for Linux users.
