To put it as simply as possible, that's because .avi is a "container" not a
"format". The container may contain files formatted in a number of different
formats and not all of them are compatible with Moviemaker or even with each
other.
In an earlier message in this thread I notice you said:

the sound will play but not the video
</quote>
My experience is that sound without video in .avi files means that a codec
is missing. Typically the missing codec is DiVX. Do you have that installed?
If not, you need the (free) DiVX codec. You can get it here:

You just need the codec--not all the other stuff they try and push onto you.
A useful utility is GSpot, a free utility that analyzes videos and tells you
what codecs you have/need to play them:

In any case, your best bet is to try converting all of the clips to a
single, known format.

Sorry, drkjedi66, John Inzer and Opinicus for intruding this thread like this and for my own use. I have been trying to find the "Post Your Question" button, I'm new here and already pretty frustrated because I couldn't find help for my problems with Movie Maker.... I really hope you don't mind, this is like my last resource.
