Document size-shift to left

hi guys,
i have flash site that exceeds the document size for publishing. I know how to change the document/stage size, however, the width ( which is the prblem) only increases to the right of the page, not evenly left/right as i need it to.

The problem is that my movies exceed the page boundary to the left hand side, and when i increase the page size it only increaes to the right and not left where i need it.

yes i could just move all the movie across so it fits, but there are heaps of scenes and animations and stuff that effected, way too much work me thinks…

I could yes scale it in DW as i have to publish to web so it fits in page, but i now need it as a Porjector file…

how can i change the page size in width and have it increase to the left and not right, perhaps even evenly???

thanks
