How do you take a video clip from a digital camera and use Windows Movie Maker to put it on YouTube?

I tried just uploading straight from the camera to YouTube but the video starts before the audio and one of the YouTube technicians told me to use Windows Movie Maker to make it better or something. How???

save ur video file onto ur computer... the open Microsofts Window Movie Maker, (came free and already installed with windows xp) and in there you can adjust the sound and picture to sync up..... though it should already sync..... or add whatever u want to it....
