In my research I discovered that there are basically three ways to install MythTV:
- Install it yourself into your already working Linux distro
- Use the KnoppMyth Live CD
- Use the MythDora Live DVD
MythDora apparently installs a complete installation of Fedora Core plus MythTV. KnoppMyth, however, seems to install a more minimal system focused on running MythTV. This was more what I was looking for, so I chose KnoppMyth.
