Force loadmovie to scale swf to 100% stage size

Hi all,
I have some external .swf’s of different dimensions. I’d like to know if there is a way to load an external swf to the stage and force it to fit to 100% the size of the stage it is loading into?

Also, is there a way to handle the antialiasing of the scaled clip to ensure smoothness / clarity. The swf’s contain both vector and jpg’s and when scaled down appear jaggy.

I hope this is clear. I’m fairly new to Flash, so any tips would be great.
