Documentation... What's that? :)

Well, maybe I need to look at that code more closely. IDLtoAVI creates a
bunch of global structures and I don't see the mechanism to protect the
contents from subsequent calls from different streams. But it could be
right in front of my nose.

Not an elegant solution but it should keep you busy until someone comes up
with a better one. Hopefully you don't have too many files to process...
