Widths (Stage, Movie, Player)

I would like to be able to detect the width of the Stage (or player, movie, etc) at runtime without having to (a) resize the stage, or (b) set the scale mode to “noScale”.

Is this possible? It seems like you would be able to simply refer to the Stage.width and get the width of the movie in whatever size window it is loaded in.

I am bringing up the window using Javascript with specified heights and widths (keeping the movie confined to those dimensions without any scaling issues). I’d like to be able to reference the width of the movie with actionscript, but as said above it isn’t working out.

Any ideas? Tips?

Thanks in advance!
