I would have to agree with another poster here, remember that 1024x768 is 
around 5 times the pixel count of 400x400. Although it should not be 
difficult to blit 1024x768 quickly, it will be if the format of the 
background image is not the same as the target buffer.
It would also be a good idea to check you are getting a hardware surface 
(sorry, in a rush, haven't looked through the code much).

I find that it is always a good idea to start at high res, if you can make 
things work there, then they will usually work in lower resolutions - get the 
hard work done early :)
