Mark Willis was kind enough to write a little program called Targa 32 which
will composite alpha channel masks with a sequence of images and you can do
many other things as well. You can also use it to mask an image with an
alpha channel and composite it against a series of targas for a background
as well.
It only works with targa files however, not AVI's. As far as getting
Premiere to do compositing I think it can be done but most people use After
Effects for this.
Check it out it's very useful. You can find his link in your old mail.
I'm to lazy right now to look for it.

it's fairly simple to do, but not obvious (especially without a manual)
First, add the background image to track A
Add the foreground anim to superimpose track 1
Add the alpha channel anim to superimpose track 2 (add another video track
if you haven't already with Projects>add/delete tracks)
Now for the trick.... select the foreground anim and goto transparency
settings (ctrl T) and select "track matte". This setting uses the video on
the next video track as an alpha channel.
simple eh... when you know how ;)
Any other problems with Premiere, just ask ;)
