Colin,
Not sure I completely understand that issue, but in a QTMovieLayer,
the movie is tied to the layer dimensions. If you resize the layer,
you resize the movie. The layer itself has a frame and a bounds
property. All you should need to do is grab [myMovieLayer bounds] or
[myMovieLayer frame] to get the new width and height.
float newWidth = [myMovieLayer bounds].size.width;
float newHeight = [myMovieLayer bounds].size.height;
You should also take a look at:
http://developer.apple.com/documentation/Cocoa/Conceptual/CoreAnimation_guide/Articles/LayerTreeHierarchy.html#/
/apple_ref/doc/uid/TP40006083-SW9
Specifically the part about autoresizing sublayers.

Hi there,
I'm using a QTMovieLayer with
[myMovieLayer setContentsGravity:kCAGravityResizeAspect];
specified.
I have a second layer that I'd like to draw on that needs to match
the resized movie that is now scaled to maintain the correct aspect
ratio. Is there a way of retrieving the resized movie bounds?
I know I can compute it myself, but it seems like there would be a
way of accessing the resized movie dimensions. I tried the
CGImageRef, but it just returns the resolution of the QTMovie.
thanks.
