The MythTV project was started in April 2002 by Isaac Richards,^[3] who explained his motivation:^[5]

Features

HDTV support

MythTV is capable of capturing HDTV streams from any source that will provide unencrypted video. This means broadcast ATSC and DVB content, as well as encrypted DVB content when using a tuner with an integrated CI module. Most U.S. cable and satellite providers use encrypted video only accessible through their own set-top boxes. Cable systems may provide some unencrypted QAM channels, but these will generally only be local broadcast stations, and not cable programming or premium channels.

OpenCable devices are available to access encrypted content on U.S. cable systems, but as this is a full DRM system, and not just CA like DVB CI, every piece of hardware and software on the playback chain must be tested and licensed by CableLabs. At current, Windows Media Center is the only DVR software to meet these requirements, and only it, and other software using its recording libraries, can use these devices. In 2010, CableLabs relaxed the DRM restrictions allowing unlicensed devices to record copy freely content using these devices,^[6] however it is still entirely up to cable operators what content they provide flagged as such.

As an alternative to direct digital capture, one can use an external decoder to receive the channels, and then capture using digital-analog-digital conversion (the analog hole). A popular means of doing this conversion is to connect the component outputs of a set-top box to the Hauppauge HD PVR.^[7]^[8]

Modules

The base system integrates well with its modules. A system can be controlled with an infrared remote control using LIRC, or radio remote control using kernel modules.

Operating systems

MythTV is available for many operating systems based on Linux or Unix, including Mac OS. The MythTV website distributes only source code, which must be compiled for the desired system; executable programs can be downloaded from various third-party sources.^[9] The software runs on and is officially supported by Microsoft Windows, but {{As of|2013|1|lc=on}} no official executable version was available; there are detailed instructions for compiling for Windows.^[10] All core frontend features work under Windows, including LiveTV, scheduling, and watching recordings, but most plugins do not work without additional patches.^[11]

Bundles

There are several projects that include a Linux distribution bundled with MythTV (and associated libraries) to make installation, configuration and maintenance easier and faster:
