As someone from an country where dubbing movies is very common. (Germany) I think its a great Idea. Some countrys don't have this tradition. I think there are just few movies dubbed in dutch.
But real dubbing is better than voice-overs :)
Did you even alter the scrolling text?
I would never assume, that I could do such a think as dubbing a movie .. or recut audio tracks to fit to the adywan edition.
