After attempting to play or access a DVD which hadn't yet been finalized, MP stopped responding and had to be terminated using Task Manager.
Perhaps this is a nit, but it would be nice to have some kind of error handling for this.
I'm afraid the logs don't show much, but I attach them anyway, just in case they're some help.
