Well, I am jealous of all those windows folks who have amazingly good GUI apps for video format conversions / transcoding. I've always wanted some good idea of how to do this under linux. How could you rip DVDs and convert them to DivX files so that you can save a copy even if the flaky and trashy optical medium dies out after a while?
Stumbled across this link while searching online.. Looks good, though a bit dated.
