Actionsript Component views in Test Movie but not in rendered AVI

Hi,

I have downloaded a smoke effect off the internet that I think is an actionscript component movie clip & have managed to get it so that I can see smoke when I test the movie in Flash, but can't see it when I have rendered it to an AVI video.

I have had a similar problem before, with symbols, which you folks on here kindly helped me solve. I think the solution was to make sure I had picked "Graphic" in the properties menu for the symbol & then "Loop". However that isn't working with this, possibly because it needs to be a movie clip (?).

I got the component from here:

http://flash-effects.com/create-smok...customisation/

I've tried following the instructions & that makes it work in Flash's "Test Movie", but still can't get it to work in any rendered video I export.

Help would be much appreciated.
