User:JeffSimpson/Upgrading from 0.19 p9163-r1 to 0.20 on Gentoo from portage overlay

Back up existing system

• Package up existing mythtv in case you need to revert back:

quickpkg media-tv/mythtv

Build new system

• Download MythTV portage overlay file from http://xxx.teppic.homelinux.net/MythTV-0.20-Overlay.tar.bz2
• Extract into portage overlay

  cp MythTV-0.20-Overlay.tar.bz2 /usr/local/portage
  cd /usr/local/portage
  tar -xjf MythTV-0.20-Overlay.tar.bz2

• Build the packages (but don't install yet):

emerge -B mythtv
