Thanks!!!. When i removed "moviesGallery.setVirtualGroups(true), i've 
executed the app, and it works!!! Now selects fine the first element.
The apps works with: 			moviesGallery.setSelection( new GalleryItem[]{ 
moviesGallery.getItem(0).getItem(number) } );

and now, i'm able to select programmatically every number i want. I 
suppose the order is:  moviesgallery.getItem(group).getItem(number of a 
item in this group). Is this right?
