Good, by the time you've finished betatesting 4.2, you'll have 5.0 ready

One additional problem (just tried with beta 9 too) "Créer une video" hangs. Same files, lowest format and quality, works with 4.0 but creation just doesn't get started with 4.2b. Direct playback works, though. (Win8, Java 1.7.0_40, I3 processor).
