KnoppMyth and MythDora are Linux distributions that aim to automate the installation of linux and MythTV. Here are screencasts of the KnoppMyth and MythDora install process. There have been claims that the current version of KnoppMyth can be installed on fast hardware in as little as 10 minutes. MythTV is an excellent open source alternative to the DVRs offered by cable companies, Windows Media Center, or Tivo."
