Cannot find demux plugin for MRL dvbpipe.m2t

Solved this by uninstalling Kaffeine through the GUI and then installed it by following the instructions at: https://help.ubuntu.com/community/Kaffeine. No more "Cannot find demux plugin for MRL dvbpipe.m2t" after this :)

I did uninstall Kaffeine through the GUI, but I do not think there is any difference between uninstalling through terminal. Here is a solution with the terminal only.

sudo apt-get remove kaffeine

sudo apt-get update && sudo apt-get upgrade

sudo apt-get install kaffeine libxine1 libxine1-all-plugins phonon-backend-xine

This solution is tested on Ubuntu Lucid (10.04) 64bit. But should work on 32bit and Ubuntu Karmic (9.10). As you may see the key in the solution is installing the extra packages "libxine1 libxine1-all-plugins phonon-backend-xine". Of course all needed packages should be installed when installing Kaffeine, but for some reason it does not.
