History

The MythTV project was started in April 2002 by Isaac Richards. Richards explained his motivation:

MythTV development is coordinated on a publicly accessible SVN server. Several official and unofficial active IRC channels and mailing lists permit communication between developers, and support for users.

Internals

The default file format for software encoding is a RTJPEG or MPEG-4 video stored in a slightly-modified version of Roman Hochleitner's NuppelVideo (.nuv) container. NUV files are also playable in VLC media player and MPlayer, but can occasionally exhibit problems in A/V synchronization due to the MythTV-specific modifications. It also appears that MythTV is now the single authority on the NuppelVideo file format, since the original author's website now appears to have been deleted. MPEG-4 is a standard used primarily to compress audio and visual (AV) digital data. ... VLC media player is a free software media player by the VideoLAN project. ... This article is about the open source media player. ...

MythTV can also record via hardware-encoder cards and other sources of MPEG-2 digital TV streams like DVB, ATSC and Firewire (from HDTV cable boxes in the US), so many users of MythTV rarely see NuppelVideo files unless they choose to transcode their files to NuppelVideo to save disk space.
