Making it all work in Kubuntu

Well, I installed Kubuntu yesterday and while the music stuff works great and it's better than windows already I still don't have all my videos playing or subtitles showing.  In one case I have wmv9 videos that don't play, in another it's just the subtitles not showing on an mkv file.  Anybody know how to make it work?

rm -Rf Kaffeine Ubuntu

Install a non-AIDS Linux distribution, like Arch Linux for a sane MPlayer.
