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?

By non-AIDS I take it you mean "no GUI and so I guess you better use the command line"?  No thanks, I would rather not spend the next week learning linux speak so I get things to work.  I did that with DOS and now what do I have to show for it?
