About video converting, before I tested "Wii Video 9" I did have a converter but I never saw the output option for *.mov.
I tried "my" converter, and what did I get? I got exactly what I wanted, the converted file was 220+MB when the original was 230+MB, picture quality is still there and I did not see any artifacts, the sound was a little lower in volume, but I bet if I convert it at 44KHz instead of the 24KHz in the end I will get the exact same file size/audio/picture quality.
Btw, the conversion took me roughly 30 minutes if not a little more, I didn't measure the time but it is roughly that.
Now all I have to do is test it on the Wii.
If you want to know what I used here are the links to it, it's shareware btw, and it can be a little confusing for beginners:
