CyTV is a streaming solution for elgato's EyeTV family of TV tuners. It allows you to watch TV and recorded programs over a wired or wireless network, and supports EyeTV USB, 200, 300, and 400. EyeTV 410, 500, 610, and Plextor's ConvertX (PX-TV402U) should also work. You can pause and resume live TV on the client ("timeshift"), and you can also change channels remotely.
