Beyond 2880?

Hello, i need to create a working flash movie 3840 px wide… or more accurately, display 2 1920px wide flash movies in one container side by side.

Flash will not allow me to create a stage file more than 2880 px wide (or properly display anything past that)

What can i do to get around this? Are there any other methods or techniques to get me a 3840px wide flash projector file?

Will Director allow this? can it call AS2 swf files and let them function properly?

What about flex? i don’t know much about it, can it do something like this?

Thanks! stuck here and need some help!
