I have a similar problem with MovieJack 3.09.303
But on my computer, under Windows XP SP1, MovieJack just freezes at 99% with some DVDs. No error message or any exception, the whole program just freezes at 99% and becomes totally unresponsive.
Furthermore I still have that stupid
"Burning error: Unsupposed return" whenever I try to record with MovieJack.
They told me they have never received a similar error but what I think is that they need to totally rewrite that awful recording engine in MovieJack.
Welcome to the world of MovieJack: Problems, problems and more problems. Oh and did I mention, bugs, bugs and more bugs?
