I have never used it, but for $70 U.S., it seems cheap enough. As CyberLink is one of the companies who provides quality CODECS for video, I should think they might have a decent product in this category.
Nothing like a Sony Vegas or Adobe Premier, but then it is not priced in that category either.
EDIT: Although you might want to look at DVD Suite 6, as it is $50 and contains the above software plus other packages.
