MythTV
About MythTV
is a collection of software that runs under the Linux operating system and provides the functions commonly known as a PVR or DVR (personal, or digital, video recorder)  essentially, it’s a computerized VCR, similar to a TiVo or a Replay.
In addition to the basic PVR functions of recording and playing back scheduled programs and allowing you to schedule recordings automatically in advance, MythTV has a plugin system that permits it to be extended by other programmers. Plugins currently exist for playing external video, viewing photos, listening to music files, using your TV and a web camera as a video-telephone over the Internet, browsing the web, retrieving current local weather, and many other functions.
