Windows Vista.

I am trying to import multiple projects into the Windows Movie Maker. I see
in the help where I can import multiple clips, but that doesn't seem to work
with multiple projects. I have these projects (3 of them) made at different
times, that I want to import into the Movie Maker so I can do the editing.
If I edit one, then try to import the second it REPLACES the 1st.

I have tried dragging and dropping on the timeline, but again it just
replaces whats there.

Is there a way to have all three projects import into the timeline at the
same time?

Now I can import the first, then open the 2nd and 3rd projects and drag and
drop on the timeline, but thats allot more work this way, And when it's all
done, there will probably be 2-3 more projects.

If the Movie Maker is not capable of this, can you recommend a commercial
(or other) program that will import multiple projects?

Thanks for any assistance
