Enter MythTV, a grand unification of personal digital video recording and home theater technology, and a magnum opus of modular design, freedom of expression and personal entertainment. At its core, MythTV is a digital video recording solution composed of several modular components that facilitate time-stretched manipulation of live television feeds, but it's really much more than that. In this multi-part article, we examine the depth and scope of MythTV's capabilities. We start here from the standard MythTV base, then address the wide-open capabilities that make MythTV more than just a video recording suite - the capabilities that make it into a quintessential home theater PC (HTPC) system.
I've installed MythTV through the mythknoppix live/cd. It worked with my TV card and was really nice but it won't replace my tivo until I need HDTV and get a TV card with a remote control.
Don't kid yourself, you will not save money with MythTV. To make a machine that can go into your living room, you will have to spend some decent pennies to buy the right kind of quiet hard drive, the right video card with remote control, the right looking case that at least looks like it belongs in the living room.
