Install according to http://buffalo.nas-central.org/wiki/Debian_on_the_Kurobox using http://buffalo.nas-central.org/wiki/Debian_sylver

Then update your apt sources (if you are not running the latest version of Debian (4.0 at the time of writing) you will need to change "stable" in the lines below for the name of your distribution (e.g. "sarge" for version 3.1), for more information visit http://wiki.debian.org/SourcesList?action=show&redirect=sources.list)

#/etc/apt/sources.list

#  Debian Main

#  Debian Security Updates

# Christian Marillat's packages (MythTV, mplayer, lame)
deb http://www.debian-multimedia.org stable main
deb-src http://www.debian-multimedia.org stable main
deb http://http.us.debian.org/debian stable main contrib non-free
deb-src http://http.us.debian.org/debian stable main contrib non-free

I've added the following to default things to Sarge in /etc/apt/apt.conf (if it is missing this can be the only contents when you create it)

APT::Default-Release "stable";

Update and sort out dependencies. I prefer to use aptitude since some of the dependencies are a little dicey, but this will work too.

apt-get update
apt-get build-dep mythtv

Download source and configure options.

apt-get source mythtv --download-only
dpkg-source -x mythtv_0.20-svn20070223-0.0.dsc
cd mythtv-0.20-svn20070223
echo --disable-altivec > config.opts

The curent patch to allow compilation for the release-20-fixes branch in a file I called KuroHG-DisableAltivec.patch
