Changes to SWF

I need to make changes to a software i have about a slideshow in flash. 1. I got the problem that if my monitor is small ( like 900x600pixe), the image ( for example an image of 1200x800 ) is resized automatically to fit the 900x600 pixel, well when resized in flash it's get very ugly.. maybe is a sharpening problem... 2. Sometimes the file [login to view URL] is making a request to a file undefined that of course create a 404 error... You can see the current example (with the problem) at [login to view URL] I will provide fla files of the file main and flash When assign must be done in maximum 4-5 hours.
