I've not had much luck doing this. Both Kaffeine and Miro can't decode DVDs I put in my DVD drive (just clearing that up -- I do have one), and I've already installed whatever the optional package is that is supposed to enable DVD decoding. Of course, that doesn't mean Kaffeine and Miro know that package is installed, but I didn't see any mention of manual steps needed to make the decoder package work. To put it a different way, I want to watch DVDs on my Linux laptop and I don't know how to make it work. What do I need to do?
