Answer #4
you can rescale the image with Photoshop, it seems to make the quality fairly even. At least it’s better than “zoom”.
Answer #5
960×720 should be big enough (or you can enlarge it in something like photoshop – PNG scales quite well)
in powerpoint (im using 2007, dont know where it is in older versions) on the design tab, select page size and increase the page size
