KnoppMyth is an attempt to make the installation of GNU/Linux and MythTV as trivial as possible. It includes everything needed to get your set-top box up and running in as little time as possible.
One of the features of KnoppMyth is a very quick installation process. Generally, it can be installed in 20 minutes or less, as seen in this KnoppMyth Installation screencast on MythPVR.com . Some users have reportedly installed KnoppMyth in as little as 8 minutes on higher end hardware.
KnoppMyth is a Debian based Linux distribution that uses some of the Knoppix scripts for hardware detection.
Similar in functionality to KnoppMyth, MythDora is an alternative based on Fedora.
