Technique Suggestions - Using multiple, large FLV's

Hey All -

I’m putting together a sort of choose your own destiny, interactive video in Flash. The gist of it is this: Three snowboarders come onto a screen and you get to pick which one to ride with, what tricks he does, etc. This has all been shot already and is ready ready to go.

I have each choice that could happen built in its own FLV, each one at about a MB, some bigger. I don’t want the user to see a loading sequence between each choice, I would like it to look as seamless as possible.

Does anyone have any suggestions on a good way to accomplish this?
