Mythtv

From Buffalo NAS-Central

Install according to http://www.kurobox.com/mwiki/index.php/Debian_on_the_Kurobox using http://www.kurobox.com/mwiki/index.php/Debian_sylver

Then update your apt sources

#/etc/apt/sources.list
#
#  Debian Main
#
deb http://ftp.debian.org/debian sarge 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
