LoadMovie resizing MC

Hi,

I have an MC (inside an MC) which is getting an external image loaded into it using LoadMovie. When I load the image in it resizes the MC to the size of the image.

How would I go about making the image stay the size of the MC? (so that the MC is basically a mask for the image).

I’m sure I’m missing something fairly obvious, I have been working on this constantly for weeks now - brain is a bit melted.

Cheers,
dreeft.
