I've never actually used devede, so I can't tell you anything about it. Make sure you read the documentation thoroughly. And I found this simple tutorial
on the net that may help you. All this is assuming your system is set up correctly of course.
You say you got "title 1", but what does that mean? Is it a dvd menu with only one entry? Does the disc actually play? It sounds to me like you simply failed to change the default title name to me. Can you "click" on the "title 1" with your dvd player controller?
