SWF loading SWF

Hi everyone,

I am working on a little project where my main swf loads other swfs one after the other based on the user’s choices (list of swfs, previous & next buttons).
These swfs include (1) videos with captions using the FLVPlayback component, (2) PowerPoint presentations converted to Flash, and (3) handwritten flash “mini games”.
So far, so good.
Now one particular swf (type 3) causes problems that I can’t locate. Maybe one of you has an idea?

This particular swf differs from all other swfs in the fact that it loads 3 flash videos (flv) onto its stage respectively contains these videos in its timeline (I have tried both versions so far).
Everything works as expected locally, but not on a webserver in a browser. My main swf doesn’t load the scene. Directly calling the scene in the browser works as expected. I am therefore sure that there are no typos in file names etc, no IOErrorEvent, no MIME type probs… The swf is located in a subfolder structure, all references/paths are relative:

/
/swf/02/scene_02.swf
/swf/02/video1.flv
/swf/02/video_2.flv
/swf/02/video_3.flv
main.swf

Is there a security issue with flv files? They do work in the case of my content type (1), the videos in FLVPlayback components. Any ideas?

Thanks a lot!

In case this helps, I am loading type (3) scenes using URLRequest and Loader, tried UILoader earlier with the same result.
