I've updated my KDE 4.8 backport for Debian wheezy to KDE 4.8.3 - as usual it contains amd64 and i386 packages and it's now based on the Kubuntu quantal KDE-packages.
Another addition to the Kanotix Dragonfire repository is XBMC with PVR, its xvdr-addon and vdr-plugin-xvdr:
apt-get install xbmc xbmc-addon-xvdr vdr-plugin-xvdr
