I need to make a video of a presentation.

Ideally I would like to simply video myself, and then add the slides over the picture afterwards. This seems to me to be far the simplest way of getting a timeline and a sound track, into which I can insert the presentation images. I would like to use avidemux as it is the only editor which simply takes the video from my jvc everio. Other products such as windows movie maker don't understand the format.

Please could someone point me to a very simple how to or tutorial on how to do this. I have googled again and again, but found nothing helpful, probably because I am using the wrong words.
