I'm new at anything Linux. I have an AMD64 machine; I updated to Ubuntu 9.04 from 8.10 using Ubuntu update/install. With 9.04, I installed Kdenlive 0.7.3 through Synaptic Manager. It works perfectly, and I'm very happy with what I can do. What do I gain by trying to update to 0.7.4? It sounds like people are having headaches with the update??? I also don't understand what I have to get rid of in 0.7.3 to update to 0.7.4.
