Embedding *.swf into another *.fla

[iwishiwasafish]

G'day guys,

I'm building a portfolio to showcase my work and I'm trying to embed one of my flash animations into it. I've thought about importing it into a symbol but I lose button funtionality and sound. I also lose buttons if I convert it to a video file and import it as a *.flv

I've read somewhere about Containers? But I have no idea how these work.

Has anyone got some ideas?

Cheers for any help.
