If you have video footage that you want to capture, edit, and share with friends or family (or even use professionally), you'll be happy to know that you can do it all with open source tools. I'll show you how to author a DVD that can play on most home players.
Let's say you want to create a DVD with video footage made with your camcorder (if you just want to create a photo slideshow, I'll deal with that in a bit). The first thing you'll want to do is capture the footage to your computer using Kino. Kino is a very basic video editor, but is immensely useful at capturing and exporting video.
