Google Media Server is a Google Desktop add-on that provides a way to get PC media content onto your TV. With the help of a UPnP device, Google Media Server collects all the relevant media files from your PC and makes them available over a local host. While it doesn't seem as direct as a device like SlingCatcher, it's probably a whole lot cheaper. Google Media Server is available for download here. [Google Media Server via Crunch Gear]
