createEmptyMovieClip creates it on all frames (AS2)?

I have a question regarding createEmptyMovieClip in AS2. I have a flash file separated out into sections with labels and menu buttons which allow you to move you to the relevant frame/section (which contains the information/contents relevant to that section). This works fine. What I can't work out is tha开发者_运维知识库t if I manually put a movieclip on the stage in my 'about section' and then add contents to it via AS2 then it only exists within the about us section. If I do it using createEmptyMovieClip within the actions for the about frame this works fine but it then always exists on every other frame of the project. I assume this is because it isn't actually creating it within this frame but I can't work out how to make it do this, even when i use this.createEmptyMovieClip it has exactly the same effect. I can obviously remove the movieclip completely each time a user moves to another frame that doesn't contain it but I don't want to do this as it contains a youtube video and leaving it means it doesn't have to be reloaded each time they come back.

I would be massively grateful if anyone could shed any light on this for me as I know i'm not getting how to place it correctly but i'm not sure how I should be doing it?

Thanks so much in advance,

Dave

Create the movieclip once, then set mc._visible = false; and stop the video when you don't need it.
