Vista - put a work from windows movie maker on a website and a cd rom

Hello;
I have to do a project for my school, a video with several photos, musics
and vidéos i download on internet. I will also put some messages between the
files, the photos (if it's possible); for the vidéo i use you tube, here i
can find easily what i need.

I can do that on windows movie maker; but after i have to put the video, the
result on a website we are created; and i have to be sure it will work for
that. maybe I will have to put the final video ALSO on a cd rom;

do you think it possible to do that without problem?
and for the video I import on WMM, I have maybe to put a particular extent??
I'm afraid that it work on WMM but will not work on a site; I mean everyone
with his computer must be able to open it...

if somebody could help me...
best
