ok I am new to this, I have downloaded a movie it is an avi file, I have opened it and there is sound but shows no video, is that normal or do I need to download another one???? I have Nero Express 6, but no idea how to use it, I have read through a bunch of info and instructions and nothing seems to be working, I have saved the movie to my desktop, but can not upload it once I am in Nero.

If someone could give me a simple run through on what I should do to get this burnt onto a dvd it would really be appreciated....
