iPad app landscape loading screen

I have an iPad app that only runs in landscape mode. I made this app using Flash Professional cs 5.5. I would like to have only one image for the loading screen. The image dimensions are 1024x768 and I want this image to only appear in landscape mode no matter which orientation someone is holding their iPad. Below are links to different scenarios of how the loading screen could look. In each scenario I show four images of a basic loading screen, in which each image represents a different orientation of how someone could hold their iPad. The orange square in each image represents the iPad home button.

I would prefer scenario 1, but scenario 2 works too, but I don’t want to have scenario 3 happen, where it squishes the landscape image to make it fit the portrait screen. So how do I get my loading screen to look correct?

Unfortunately I don’t own an iPad so I can’t test my app on an iPad.
