mindstorms:
I myself get 1280x960x16 and 1280x960x32 as two of the modes available on my vid card. Is there by some off chance a possibility that maybe your video card is not "gutsy" enough, or maybe is malfunctioning, the problem being just hardware? You did say it is a slower machine.
Hey, by chance, is the original image larger than the 1280x960 parameters? I understand that Blitz has problems with images larger than the graphics screen width and height. Also, since you are filling the entire screen with your image, does DrawBlock work for you (it doesn't require masking, and just throws everything up there, including the otherwise transparent default of "black".) I realize you are using ResizeImage, which does resizing to pixels rather than a percentage, but it never hurts to check your assumptions. After resizing, is the resized image actually at the width and height you set?
