Hey Matt - No worries.
It seems like the best approach is to do as you suggest and handle the aspect resizing of the layer myself - that way I can maintain the same dimensions with the drawing layer. It'd be interesting to have some sort of insight as to what's actually changing then - it seems that QTMovieLayer is handling the transformations internally - but I wonder what ramifications this would have if you were drawing your own content on a CALayer. It seems like it would be ideal to be able to access this information. cheers. On Thu, Oct 9, 2008 at 8:15 AM, Matt Long <[EMAIL PROTECTED]> wrote: > Colin, > > My assumptions were totally wrong.
