No difference at all.

Once the image is loaded up you could use the formattedWidth &  
formattedHeight. To do so before loading the image (on OS X 10) you  
could use SIPS via a shell call to get the pixel dimensions of the  
image.

I've done this before now as you also get the ability to load up  
TIFFs, PDFs etc, but it tends to be a bit clunky in comparison to the  
native handling of images.

Masks and partial transparency, for example, won't work with a player  
object. I also ran into problems when trying to combine scaled players  
and visual effects for a slideshow app - but that was quite a long  
time ago and is probably a lot better - it may even have been before  
Core Image visual effects were added.
