CS4, AS3 (and 2), how import 3D tweens into AS2

Hello All !
I created an animation using 3d tweens (in AS3 obviously)
however I would like to use this animation in an old AS2 website
that I have. I tried importing it in various ways (SWF,FLV,MOV, even
a GIF sequence) but non of these are producing anything close to
acceptable... of course if I just drag the layer in the whole tween gets
screwed up.

what would be the best way to do this ?

(I don't want to change my whole AS2 site into AS3 just for a 2 sec animation)

Thank you very much for all and any replies.

Cheers !:p
